Windows 10 x64 home, Nvidia GTX 1070 with latest WHQL dirver
Short description of error
MixRGB node still keeps in memory both input textures no matter what "Fac" value is - "0" or "1". This leads to large memory (VRAM in my case) consumption if there is two large textures connected.
Exact steps for others to reproduce the error
- Open attached file, in material "Problem example" set slider to "0" and switch viewport mode to "Render". Check memory consumption.
- Set same slider to "1" and again switch viewport mode to "Render". Check memory consumption.
- Optional - switch object material from "Problem example" to "Hack to fix problem" and repeat points 1. and 2. - this time memory consumption will be correct.
