oompa_l Posted October 30, 2015 Share Posted October 30, 2015 I am attempting a night rendering and I am encountering something I've never seen before - vray for sketchup is generating halo shaped splotches on an exterior opaque surface. they have a strong resemblance to blood cellls. No idea what's going on and searching for vray blood cells isn't working either any advice is truly appreciated Link to comment Share on other sites More sharing options...

augustobohm Posted November 3, 2015 Share Posted November 3, 2015 I don't know exacly the problem, but post a bigger image so we can see better the issues... i'm 90% sure it is a light problem, how many lights do you have in the scene? Link to comment Share on other sites More sharing options...
oompa_l Posted November 3, 2015 Author Share Posted November 3, 2015 thanks Augusto. I thought it might be a light issue too. I tried first turning these thin solids (metal panel) into deeper solids thinking light was bouncing around too much...thought that got it but it didnt. I just tried turning secondary bounces (GI) to 0 and it seems to have solved that part of the problem...is there a better way to achieve this? see higher res image of problem Link to comment Share on other sites More sharing options...
augustobohm Posted November 3, 2015 Share Posted November 3, 2015 Did you also have an environment map on the scene? Or a dome light with a map? Link to comment Share on other sites More sharing options...
Devin Johnston Posted November 3, 2015 Share Posted November 3, 2015 It's your GI settings there too low you need to smooth it out. Link to comment Share on other sites More sharing options...
oompa_l Posted November 3, 2015 Author Share Posted November 3, 2015 yes, there's an environment map. both the GI and Reflection/refraction are set to bitmaps. why? Link to comment Share on other sites More sharing options...
oompa_l Posted November 3, 2015 Author Share Posted November 3, 2015 what do you recommend for GI settings? Link to comment Share on other sites More sharing options...
Chris MacDonald Posted November 9, 2015 Share Posted November 9, 2015 Mostly I recommend reading the VRay manual. I realise this sounds profoundly unhelpful, but then so are "use these settings" posts. I know which will benefit you more in the long term.
