Elena_ DeCosta Posted January 19, 2015 Share Posted January 19, 2015 hi everybody After a along time i tried to comp my sequence in Houdini but i am totally get upset. my whole sequence came out from Maya is pixelated (find in image) i change every thing but nothing help. even i off, "fast interactive cooking". no use.my renders are coming out like this (find in image). please can anybody give idea whats wrong with Houdini or my understanding or i should attache with nuke or fusion. Houdini is not for any comp. thanks friends for helping me earlier. Quote Link to comment Share on other sites More sharing options...
edward Posted January 19, 2015 Share Posted January 19, 2015 It's impossible to see the problem when you post scaled down jpeg images. From your screenshot, are you're asking in COPs is to load the image and apply some gamma on top right? If it's pixelated already, my guess is that the input images have already been quantized even before being loaded into Houdini. Quote Link to comment Share on other sites More sharing options...
Elena_ DeCosta Posted January 20, 2015 Author Share Posted January 20, 2015 Thanks a lot Mr edward for helping me out. Please find some more images. I am just importing the image in COP but question is why i am getting very low image quality.Even same happening when i am rendering from the COP . Please find the image i am comparing with fusion.I am sure there is something I am missing. Quote Link to comment Share on other sites More sharing options...
Elena_ DeCosta Posted January 20, 2015 Author Share Posted January 20, 2015 please find the original sequence file. The format is tiff and its not permitted so i converted into jpeg. you can see the difference in jpeg too. thanks Quote Link to comment Share on other sites More sharing options...
mestela Posted January 20, 2015 Share Posted January 20, 2015 (edited) maybe post one of your images here with a .hip file, would be easier to debug that way. (edit) ah, you already did just as I posted! will have a look. Edited January 20, 2015 by mestela Quote Link to comment Share on other sites More sharing options...
mestela Posted January 20, 2015 Share Posted January 20, 2015 Yep, I can see that too, odd. Even just reading the image, than writing it straight out again, there's banding. I haven't used houdini's comp stuff much, does it not like 8 bit images? Have you tried floating point exrs? Quote Link to comment Share on other sites More sharing options...
Elena_ DeCosta Posted January 20, 2015 Author Share Posted January 20, 2015 (edited) yeah .exr doesn't seems have that problem. In others thread my friend are saying its a bug of prestigious houdini. how it could be a bug its most simple or a basic thing(importing file for compositing). And why side effects don't want us to comp in tiff or tga , its silly. Anyway when i am rendering image into .exr and importing in houdini, i got increased gamma and same time not getting any COPs for color space. so solution is, i should attache with nuke or fusion only.

pezetko Posted January 20, 2015 Share Posted January 20, 2015 With "pixelated " do you mean that there is banding? Try Turn off "Linearize Non-Linear Images" on File COP, then attach Convert COP, set Raster Depth to 16 Bit Floating Point and then add Gamma COP with Gamma set to 1/2.2.

Elena_ DeCosta Posted January 20, 2015 Author Share Posted January 20, 2015 Thanks pezetko ,yeah its banding. Yes some how your way just did the job but curious to know is this the way to comp (prcedural process) in houdini. OR its trick to solve the issue. Actually i have many import COPs (i.e 20 to 30). And again i will put convert and gamma COP with every Import COPs , i am afraid it could be problem of memory. but again thanks. Quote Link to comment Share on other sites More sharing options...
rayman Posted January 20, 2015 Share Posted January 20, 2015 You can do it Houdini way and just put them into an asset. 1 Quote Link to comment Share on other sites More sharing options...
