Raudel Solis Posted February 7, 2013 Posted February 7, 2013 I got this Issue with black boxes that only appears when Irradiance Map, Light Cache, or Photon Map is used as the Primary GI Engine. The issue does not exist when Brute force is used in the Primary GI engine. The following renders are Low quality, but show the issue. /.\ Can anyone help? ---- update -------- All 4 Primary GI engines do this /.\ -------- Update ------------ \^O^/ Vray Frame buffer solves the issue Quote
Andrew1979 Posted February 7, 2013 Posted February 7, 2013 Are they the final images or just in the process of rendering? Are you using all Vray Materials and not raytraced ones? Quote
george monsoon Posted February 7, 2013 Posted February 7, 2013 I get problems with blotches in low light scenes. What kind of light are you using for the scene? Also, in the render settings ensure you have "default lighting" turned off. Quote
Raudel Solis Posted February 7, 2013 Author Posted February 7, 2013 [quote name= Also, in the render settings ensure you have "default lighting" turned off.[/quote] I nearly face palmed, I saw my default lighting was set to Off with Gi, but it's the same as Off. The difference between off With Gi is that when there are no lights the default lights turn on. when 1 light exist Default lights turn off /.\ Nice idea, but that's not what's causing the issue.

Raudel Solis Posted February 7, 2013 Author Posted February 7, 2013 Are they the final images or just in the process of rendering? Are you using all Vray Materials and not raytraced ones? All vray materials, blocks are throughout the entire scene so it's not a material issue. the blocks are also uniform for the most part. Quote
Raudel Solis Posted February 7, 2013 Author Posted February 7, 2013 maybe you can upload your file I would, but the scene itself is 70Mb, "only the materials used" in the scene are about 20Mb, The Scene folder with the scene and its assets is 129Mb /.\ Quote
Raudel Solis Posted February 7, 2013 Author Posted February 7, 2013 (edited) Well i thought the vray frame buffer solves the issue, for the most part it did. One thing i noticed though was after i left my computer rendering two images in the .tga format with a 32 bit depth, the .tga files had the blocky artifacts. I had the frame buffer with the rendered scene and in the frame buffer then blocky artifacts were non existent. For this reason i decided to save the image in the .png format and "lo and behold " the image is free of unwanted artifacts. There is something about the bit depth that affects this. I just don't know what. I've never experienced this issue until yesterday which was a time of great change in this scene. Edited February 8, 2013 by Raudel Solis Quote
Raudel Solis Posted February 7, 2013 Author Posted February 7, 2013 "Check out mah pots" The previous statement was a quote meant to be read as it is spelled. "Admit it after reading this line you will realize that you read this line the wrong way, and not the way you were suppose to read it.. Furthermore you probably read read as read and read as read". Forgot to attach "Mah pots" here they are: Quote
