So, we are trying to get the grass working again and in doing so have run into some issues.
This is done with a PNG file exported and no alpha associated with it at all. I know that is an issue so we have tried to use several different options and none of them seem to work. I have saved this out to be a TGA with an alpha channel and I have saved it as a DXT5, but none of them are working.
We are attempting to load the alpha's via premultiplied rednering. Is this the proper technique? Should we be doing something else? Is there a setup we need to use so our alpha's can load with these texture formats?
Furthermore, we read that premultiplied works with DXT4 and DXT2 but the photoshop plugin that lets me make DDS files does not have an option to export as DXT4 or DXT2, only 1, 3, or 5. Thanks for your help with this as this is a very annoying problem.
Note: I have tried to save this out using superPNG but when I do it removes the background and doesnt keep the alpha layer, even though i told it to do so....
