Mental ray overlapping grids - dr_ron - 02-04-2015 Hi i am having issues with overlapping Fume grids with mental ray. We are currently re-doing a project from final render to mental ray. Final render with Fusionworks is fine. Now with mental ray im getting black box with harsh line in the overlap. This is just a small test scene to show you the problem. Default MR setting in Max with Autovolume on. Running: Max 2014 Fume 3.5.4 Any suggestions? image uploaded. [ATTACHMENT NOT FOUND] thanks for any help ps...we have to use mental ray :$ Re: Mental ray overlapping grids - sitnisati - 02-05-2015 Hello, There could be one more thing other than Autovolume. Make sure that grids does not perfectly overlap on any axes... this can make issue with any renderer. Please let me know. Regards, Kresimir Tkalcec Re: Mental ray overlapping grids - dr_ron - 02-05-2015 Hi iv tried various rotations of both grids and still get the error Here is first frame render [ATTACHMENT NOT FOUND] thanks for reply Harv Re: Mental ray overlapping grids - dr_ron - 02-05-2015 if it helps, here are the files [ATTACHMENT NOT FOUND] Re: Mental ray overlapping grids - sitnisati - 02-05-2015 Thank you for the scene. We will look into this, but it seems that both volumes are not mixing at all - they're just overlapped depending on which grid was rendered last. I'm not sure what we can do about it. A simple scene made out of yours is attached. Render frame 0 and frame 1 and see the difference. The difference is only a slightly changed location of one of the grids. Regards, Kresimir Tkalcec Re: Mental ray overlapping grids - dr_ron - 02-06-2015 Hi Kresimir thanks for taking a look at this. I take it that this is a mental ray issue then Thanks for your time Harv Re: Mental ray overlapping grids - sitnisati - 02-06-2015 You're welcome. I think this would blend properly in FumeFX/mental ray for Maya as mr implementation is different there. We'll look into this for 3ds max to see if there is a solution. Regards, Kresimir Tkalcec Re: Mental ray overlapping grids - dr_ron - 02-06-2015 Thanks again.
