png texture with alpha channel but the transparency seems to be white.
How do I let the transparency in the png texture look through to the background?(alpha blend)
I'm trying to put some text on a glass using 3d functionality of Photoshop. Is there any way to do so? On non-transparent material it is quite easy I can choose color of material then put texture with some text on a model. But how to put a non-transparent text texture on a transparent material?
I mean something like that that [i used a picture from Daniel Presedo's video tutorial and added text with distort and warp
I'm developing a tile based game, I have basic ground tiles, and above these tiles can be objects. My game engine supports objects with an alpha channel, where the alpha channel is used for transparency:
alphachannel 0 = completely invisible pixel
alphachannel 255 = opaque pixel
alphachannel between 0 and 255 means the object and the background tile below that are blended, like semi-transparency.
This is useful to give the objects soft edges, and for semi-transparant fire, ghosts, and other nice looking effects. Code:
I'm trying to do something that I could previously do with other image software. I want to 'paint' the transparency of a layer using the alpha channel. So when I paint black on the alpha channel it makes that part of the layer completely transparent, and white makes it completely opaque (and grey shades are in between). From what I understood of the help, this should be possible by just creating an alpha channel and painting in it. But when I try and then click back to display the RGB channel to look at the changes I've made, nothing actually changes. Whatever I seem to do to the alpha channel it doesn't actually affect the layer's transpancy at all.

What am I doing wrong?
Is there any way I can directly make a grayscale image into an alpha transparency channel?
I mean, NOT involving selection? Because selection by color to layer mask,is really difficult what I need to do the selection threshold.
Why is it easy to turn an alpha channel into a grayscale image but not the reverse?
I already have an image file in png format..which I want to use as an application launcher icon for my android application.
The android specifies image with following properties for the launcher icon(Will need 4 different image to support different screen size in mobile devices)

I was simply wondering the best means in Paint.Net to use a black and white image and use it as the alpha channel of my image, with white being opaque and black being fully transparent. I looked through the plugins on the site and didn't see anything that seemed to resemble what I was after.
View 2 Replies View RelatedI'm attempting to render a series of images in the cloud and my plan is to take these images into Photoshop so that I can apply a background from an image I possess.
To do this I need the background to be a plain white background, export as a TIFF or PNG, then add an alpha channel in Photoshop. The problem is that whatever settings I apply in Revit, the cloud rendering always gives me the standard grey / blue horizon background. I have changed the render settings using the render setup, through the view properties, through the graphic display, still no joy....
I'm trying to make a texture for a model in a video game, and I want some of it to be transparent. This is done by editing a text file that tells the model to use the textures alpha channel. things in the alpha channel that are white are transparent and things that are black aren't.
But I don't really know how to edit the textures alpha. Here is a video I've seen that explains how to make one in photoshop: [URL]......
How to do exactly what he does in gimp? whenever i duplicate one of the rgb layers, it isn't black and white like it is in ps. i'm also not sure how to have it turn into the alpha.
How can I set transparency like when color is brighter it will be more transparent, eg. white is fully transparent, black is non-transparent, gray is 50% transparent, etc..
I would save png after that.
For quite some time I've been trying to find the best way to remove a white background from images. I've checked out the sticky thread on this forum and as my image isn't of great quality and because it features quite a lot of white that won't apply.
Recently I found this tutorial which is supposed to work great (as seen in the comments). However, I think that because of a GIMP update that won't apply anymore somehow. I was hoping you guys might know what was causing it.
Everything works well until I get to step 7, where I have to select to Alpha. There it selects just the outlines, but my selection includes inner parts of the image, not just the background. And then after I invert and delete, the white that remains still has transparent parts that show up on the upper layer. So, am I doing something wrong with the Alpha to Selection, is that tutorial updated or is there a better way to remove the background from ie. a logo with just one background colour which isn't of great quality.
im trying to add an alpha layer or alpha channel to a bitmap and save in BMP format.

View 1 Replies View Relatedany difference between alpha layer and alpha channel? I mean has to be right? I just don't know what exactly that would be if there is. I'm trying to figure out some more stable uses for computer graphics when building textures with alpha layer or alpha channels. So far I get a flicker from opengl bug when using alphas. So I'm wondering if I use Alpha layer and something with a solid color underneath the geometry if I could achieve a more stable result where alpha sorting. Possibly clearing it up where my alpha layered geometry stays on top vs bleeding through at times it seems.

View 1 Replies View RelatedI have created two masks with channels to use on an image. Now I want to combine the two channel masks into one to use. I made a new layer in channels of the composite masks which gave me an Alpha channel. The Alpha channels show the solid black paint lines where I filled in the selection voids. These solid lines affected the adjustment layers so I ended up doing some erasing at 50%. Not the shortest workflow direction. How can I combine two channel masks (selections) into a common selection and save as a new Channel?
View 7 Replies View RelatedI created an alpha channel with marquee tool on a colored backgound, by using "select > save selection", the alpha channel appeared at the bottom of the channel palette. I know the white part should represents transparency and the black part is opaque. But when I import this into the Adobe premiere6.5, the thing is reversed, I have to use "alpha channel" plus "reverse" option to get what I want - see through the "white" part. I heard there is an option in the photoshop with which you can define whether you want "white" is transparent,black is opaque or vice versa,
View 8 Replies View RelatedI have an image that I want to have an alpha channel even though it isn't used at all. Even if I save the image with transparency flag in "Save for web" (as PNG), Photoshop doesn't include the alpha channel with image because it's not been used.

View 5 Replies View RelatedOnce I create an alpha channel, how do I edit it? I have tried selecting and clicking the alpha channel, and then using the paintbrush tool. I understand that if I have a white foreground, painting should remove some of the mask, while a black background should result in the painting adding to the mask. But often nothing seems to happen when I paint. Or, at other times, the painting results in paint marks on my image but doesn't affect the "marching ants" and therefore doesn't affect the mask. I have already checked that my K setting in Color is at 0 for white and 100 for black. Using CS5 version 13.0 x64 with Windows 7.

I have Corel Motion 3D and some of the kbase was suggesting I needed to use that to export with the alpha channel but it would be a lot simpler to be able to push it out from X4. Even if I can do it as non-flash file I can take it to something like Ijoysoft and convert to flash.
I've seen instructions to use this but I'm not sure what its core purpose is and I can't seem to find a definition in the user manual, online or in this forum.

This is the instruction manual of the template:
------
Once you have completed the painting work on your Texture Template, be sure to save it in its original form as a layered .psd document. Then, "flatten" the image, and save as a .bmp file with the name you wish to use for your paint scheme. Example: "DFB58_N12345.bmp". This name indicates that the template is for the DreamFleet (DF) Baron 58 (B58), and the N1234 is the registration number you painted on the aircraft. If you are doing a livery for an airliner, you can substitute the name of the airline for the registration number.
The name is not important, and DreamManager will work with any name, however we suggest a logical name so that you and others will know what the texture is. With little doubt, after all this painting work, you may wish to share your texture with others by uploading it to a file library, thus, a logical name will help identify it.
With your Texture Template now saved with a proper name and as a .bmp file, it is now time to prepare the Alpha Channel template.
Re-open the .psd version of the template in your paint program, and using whatever means you feel comfortable with, copy the entire alpha channel only to a new document. Once in the new document as a standard image layer, flatten the image, convert to grey scale if necessary, and then save this file as a .bmp file, the same as you did with your Texture Template. Use the same name that you used with the Texture Template, except add the suffix "_A" at the end of the name. If you have done this properly, your alpha channel template will be the same size as your Texture Template (typically 4096 x 1024).
Example:
Name of your Texture Template: DFB58_N12345.bmp
Name of your Alpha Channel Template: DFB58_N12345_A.bmp
