Hello everyone,
i think it is no secret that generally all textures must have the size format which is the power of 2 (256x256, 512x512, 1024x1024 ...)
sometimes a little more space is needed but not so much, that the next size is necessary. A size of for example 1024x512 is also supported and for hair textures reasonable.

is there any disadvantage to use unequal lenght of x- an y-side (like 1024x512) for one texture or is there no problem with it?

thanks for your help in advance

afaik no problem

there are no problems

ok thx for the info, i was afraid that maybe more ram is used than actually needed
