Hi!!

How can i speed up the texture lookup of mantra, is very slow; I have test a basic scene with a 4K texture in a basic material, mantra takes 10 sec to call a texture from disk, renderman only 2 sec; why?

Thanks.

Hi alejandro,


What format is the texture saved as?

.rat files are the most effiencent for Houdini.

Mantra converts any other texture to rat, before rendering, that's why delay you see. As Jacob says, always use rats, and you'll be fine.

Hi!!

Thank you very much for the help.

I have used mplay to convert my textures to a .rat format; the problem is: when i try to save the texture to a .rat format by choose it from the option menu of the output window of Mplay, mantra is slow with this texture, but if directly put .rat in the file name, mantra is now fast; is this a bug?

when i use the option menu my texture size is 20,921.
when i don´t use the option menu the size is 20,754.

Thank you!!!
