Using 8K textures makes for big image files.............. :-\
But it looks freakin awesome....
Details certainly seem worth it and the mix of reds and greens look nice.
That is actually 4 surface layers using 8K image maps..........still learning how to use them. That scatter shader I read about on the wish list just got another vote. ;D
By the way the pic was almost 4MB in its original form...........the post was at quality 5 out of PS. ???
I do not think I used anything beyond 2048 and at a slight distance the texture maps look passable enough. With scatter another aspect is blending textures into something more detailed and complex therefore not having the need of using such large texture maps. Of course that will not apply to everything but I think it should help with more organically random and natural textures.
I thought there was a thread somewhere about optimizing image sizes within Photoshop or Photoshop alternative?
