(done, open) [HOU-1774, HOU-1804] tx mipmaps

[LeoYfver]

Is there a global mipmap contol for the quality of the mipmaps? Is the filter blur the control for that per iamge texture?

If thats the case can somebody help me to write a python translate code for changing that during rendertime? could not figure out how to do it.

Regards Alexis

Hello LeoYfver , looks like we missed this one, I've added in our system and will inform you once the option is added. Thanks for the feedback.

[LeoYfver]

chakarov thanks! Do you know also how i can change the filter blur on all textures with post translate?

[LeoYfver]

the goal is to be able to lower the mipmap levels on things that are in phantom and matte.

The control is already in the nightlies (under ROP->Renderer->Options->Textures).

Hello LeoYfver , here it is a simple post translate script for override filter blur for all imageFiles. I will try to find a way to control mipmap levels for mates and phantom only.

[LeoYfver]

thansk so much for helping out with the script! Will also test the global control when we will download the latest nightly

Hi again LeoYfver, currently there is no way tо control mipmap resolution per-imageFile , only globally.

[LeoYfver]

chakarov on the image file isnt that what the blur value does? or do you mean with pythontranslate we cant control the filter_blur when they are in phantom or matte per object?

[chakarov]

No, blur value is for blurring the image, not for changing resolution.

[LeoYfver]

i think it does, atleast from what i understand.

the left one has blur 3 and the right one has 0.2. I use a debug tx texture.

here is the debug texture

Hello and sorry about my mistake. We do not use it much and completely forgot about this feature. Anyway I will ask some of the developers if they can help with the script. Because of the Houdini nature this can be very complicated. What about materials assigned to mate and nonmate objects?

[LeoYfver]

no worries yes that seems to be the way to check which imagefiles are connected to phantom and matte objects. Im just not smart enough to figure how to do it with python translate :P

[LeoYfver]

tried the global mipmap resolution control and it works. Now it caps the resolution to a certain number, what i would like is it do downgrade all of the textures 1 step. So if you have a texture which is 8k and another which is 4k the 8k would become 4k and the 4k would become 2k. Now it just caps both to 4k if thats the resolution chosen.

[LeoYfver]

just to be clear, both controls are really nice to have
