How to import / use 16bit PER CHANNEL (ARGB64) texture in unity?
Hello,
I can't seem to find a way to import 16 bits (per channel, not per image) textures into unity and really need this for detailed displacement maps with heavy tessellation, am i missing something or is it not supported?
I've seen references to ARGBHalf but all i can find on the net relating to this in unity is for RenderTextures only, nothing about plain regular 16 bit per channel imported png or similar.
Thanks!
I'm sorry to say I don't think this is supported. :-/
The list of supported formats for normal Texture2Ds is available here and does not seem to include a 64 bit that has 16 bits per channel. I don't know why the RenderTextureFormat supports one and the Texture2D does not.
Well that's too bad as 8bit per channel is way way way way way (did i mention way?) too low for the use i have atm :( Can you think of any workarounds? I have a displacement texture and i get terraced areas which should be smooth because the smallest displacement unity is huge at this channel resolution. I'm going to Normalize the alpha channel but i can only help so much (maybe *3 or so the precision vs current image, but i could use *100). In any case this seems to be the answer so marking it as such.
How about using two textures? One for the first 8 bits of accuracy and the second for the next 8 bits of accuracy. Then combine them as follows:
float posX = texture1[pixel].r + texture2[pixel].r /256;
