up4 Posted October 2, 2014 Share Posted October 2, 2014 Hi all, So, to futureproof digital assets (say to support both Mantra and Arnold) and also to get the best downscaling filter possible (say Lanczos6, if that is not already what iconvert uses) should I (is it even possible with Mantra?) use EXR mipmaps (generated with maketx)? If I cannot use EXR mipmaps with Mantra, can Cortex' RATWriter be used to write a batch-converter or a Nuke plugin to write Lanczos6-filtered RAT mipmaps? Thanks!

symek Posted September 28, 2016 Share Posted September 28, 2016 Can you be more specific, what else you need to know besides what was mentioned on SESI forum? Quote Link to comment Share on other sites More sharing options...
homeless3d Posted September 29, 2016 Share Posted September 29, 2016 The SESI post is a bit old I think. I have tiled and mipmaped exrs (a lot) 7 textures with UDIMs(160 tiles each one of them) . The setup is for htoa and i want to port it to mantra. Anyone knows why is not possible for mantra to use the exr versions? If thats the case, do I need to write a python to convert all of them ?
