Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

A lot of shaders compiling


I know that this problem was discussed many times , but the last solution i've seen is update to 4.1.1 with fix for this issue , though i am on 4.3.1 version and i still have this problem. I have landscape material with layer texture system to paint on the landscape. So i have about 10 textures and this is the material grid : https://dl.dropboxusercontent.com/s/0l870db2yxc4q9i/shot_140816_153030.png

The problem is that simply changing one constant value to tweak material re-compiles about 3200 shaders ! It takes about 2 minutes but imagine the fine-tweaking of this material ... Problem is only for this material , others are fine.

Specs of my PC are pretty high , it is lenovo Y50-70 notebook, i7-4710HQ with GTX 860M on board. I've read one solution about saving material first and than hitting the apply button. That reduced amount of shaders to compile from 3700+ to 3200+ , though still that is pretty much ? Is there a way to check where is the problem , maybe something in my grid is incorrect ?

Thanks in advance !

Also i have a guess about that - one "patch" of my terrain takes about 340 shaders to recompile , when i draw on it , so seems that 3200+ shaders are 9-10 patches of terrain , each of them with shader recompiled , that guess is correct ?
