How to DDS?

[Spiritian]

I looked at his alpha channel . . . it isnt a simple edit what there already was, but a complete new one.

 

 

OK I tested how to make texture aplha channel "transparent"

But how to create one from scratch? with the image you have createed?

I don't think you understand how plants are simulated in games. Usually, textures are mapped onto a plane or group of planes and use the alpha transparency mask to simulate strands, branches, leaves, etc.. You can completely change the way a shrub looks just by repainting the texture and its alpha channel, there's no need to change a mesh if its just a group of planes. Edited January 2, 2012 by Sunnie

Yes, I realized that when I did some research . . . . but that doesnt explain to me how to create an alpha channel of what I made and save it properly, Because I did a simple test where I just changed the alpha channel with white paint but then it didnt want to save.

In each picture file you normally have 3 channels, red, green, and blue. if you are going to use said picture in an application that can readu an alpha channel, it is an additional channel that is used to make transparencies in the combined RGB channels. Alpha channels translates transparency amount by using a gray scale where black is fully transparent and white is fully opaque. In Photoshop, you can easliy add an alpha channel by clicking the channels tab in the navigator and clicking the new channel button at the bottom. Whan you export the image as a DDS, make sure you save in DXT3 or DXT5 ARGB.

So will the following work?

 

I make a cutout of my image, Now I take the cutout shape - place it on the alpha channel and colour it in with white and save it in those that you said?

[Spiritian]

It worked :woot: Yay

 

Thanks a bunch sunnie for helpfull advice, gave Kudos.

 

Now i am not limited in my creations :D

I know this is one heck of a necro post - but on the slight chance that anyone has found this page and still needs answers,
I threw together a Guide on Steam (you won't need a login to see it). Hope it helps :D
