I have a tiled EXR that i’m loading into the maya file image node, than connecting that into the diffuse color of the VRay material. How do i tell the tiled exr is actually working and what is the “official” workflow for using tiled exr’s in vray ? The VRay for maya manual is pretty sparse on the su…

I’m interested in knowing this too. I converted all my TIFs (300+ 2K textures) to tiled EXRs and expected the memory consumption will go down during render time, but found that it seems to consume the same amount of memory.

Did you generate mip-maps for your tiled OpenEXR files (or, which tool did you use to write the file and with what options)? This is the correct workflow - there is nothing special to it. Best regards, Vlado

They need to also include mip-maps; writing just a tiled file without mip-maps will make no difference. We could probably add a warning in this case. Best regards, Vlado

How should I include the mip-maps during the converting process? I am using the GUI version of the img2tiledexr tool and I didn’t see option for choosing the filter type for converted exrs? Edit: or the converted EXRs are automatically teiled mipmap EXRs? What I then need to do is specify the filte…

By default imgtotiledexr writes out tiled mipmaps. You have to specifiy on the file read node. Change from quadratic to mipmap and you should be good. Also under the settings tab of V-Ray globals, under systems. Set geometry to dynamic and give it a memory limit. You might have it on automati…

pure gold, Scott. Really appreciate your input. I will give a shot tomorrow early morning. The asset I am dealing with has 300+ 2k tif textures across 20+ UV tiles. During render time, it eat up about 9.5 GB of RAM even with displacement and subdivision set to Edge length of 4 and Max subdivs of 1 (…

I haven’t done anything with displacement from Mudbox. Only zbrush. But I know that you don’t have to set a min and max displacement value if you paint maps at the scale you are going to render at. So if a someone gets a model to paint, make sure its in centimeters when they paint it. Becareful …

I changed all original TIF maps to tiled mipmap EXRs except the normal and displacement maps. Unfortunately, the scene consumed about the same, if not more, RAM to render.

[image] VRAY & Rhino System If you used img2tiledexr, then they have mip-maps by default. You need to set the filtering mode to “Mip-map” and make sure that texture filtering is enabled in the V-Ray settings. Best regards, Vlado Thanks, Vlado. I’ve applied the setting accordingly. However, t…

Then it may not be textures that are the problem; if you can get us the scene in question to vraymaya@chaosgroup.com we will be able to tell you more.

Best regards,
