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"

Differences in brightness of meshes

Howdy :D i tried building a room using some prepared parts i modeled using cinema4D, they are quite simple as you can see and they have the same material (all options are the same too) but i still get those differences in brightness. It would be awesome if someone had an idea how to fix this! :)

I can't really tell what the issue from just the screenshot. It can be that your wall UV are not using 0 to 1 space, and they are overlapping. Maybe your light is not bouncing properly, did you try to use a skylight? Can you post images of your lighting setup, and you meshes UV?

Hi Night Watcher :) the uvs and the setup should be ok i think: alt text alt text alt text

I noticed that the error disappears when i adjust the Indirect Lighting cache Quality from ILCQ Point to ILCQ Off. If i change the setting to ILCQ Volume the difference in brightness is far less noticable. Maybe that can help in figuring out the source of the problem and in finding a solution. alt text

Let me know if you need more detailed screenshots of the settings from the lightsources :)

Also what do you mean by difference in brightness, can point out the two areas that have a different brightness?
