Question What Does He Mean ???

i'm lately creating my own textures for my 3d models.
because my english sucks i have a question of a text i found.
.................................................. ................................................
Here are the unwrapped meshes, ready to be painted on. Within Photoshop I start out by copying the alpha channel into a normal layer and set it to Multiply. This way the black wireframe will show but everything that is white will be transparent, allowing you to see what you're painting. This layer will be the topmost one and always locked to prevent accidental painting. .

OK, dead easy this one I think. I can't get the link to show up though, but I'll do my best just based on the text you've posted.

What he's refering to is flattened wireframe UVW Maps from a model.

When he exported the maps from his 3D software to an image they saved the wireframe images to the alpha channel instead of into the main image data.

So, all he's saying is that you should go into the channels palette, make a selection of the image, copy the Alpha channel, and then paste this into the layers palette. Once that is done he's saying to set your new layer to the multiply blending mode so that only the lines can be seen upon any layers you put below it.

Not the way I usually do it though, but it works fine for him evidently.

Open your 'channels' rollout.
Select the Alpha Channel (Default Alpha 1?)
Select All
Copy it and paste it into a new layer
Just under the 'Layers' tab is a drop-down box that should say 'normal'.
Change it to 'Multiply' and that should be it.

I think this is how it's done! Hope I've helped!


- oh just remembered, if you're working with BMP's they won't have an Alpha Channel. You have to export from your 3d program as a TGA with an Alpha channel...
