By resampling your picture, you'll add more pixels and you'll have more control on the result. Adding a Mosaic effect on a low definition picture will not give the same control.
thx for the answer.
but i would like to keep this as last option because my texture is a sequence of 1000 frames 2000x2000 pixels.
i have 8 different animations, so 8000 frames.
if i resize those i am gonna nedd huge disk space!

In my example I've used the Pixel shader from Cinema. I've set the tiles in U and V with the dimensions of the texture.
After this you just have to set the "Render size" in "C4D shaders" tab to something bigger (1K, 2K, 4k).
The bigger the setting, the crisper the image becomes. The downside is that you use a lot more memory.

thx dude, but are you sure about this? because whene i use the pixel shader i just obtain a black texture in renders done with octane

you can't use image texture under a c4d shader, but c4d images works

thx you very much for you help guys i really appreciate that!
this method is really interesting unluckyly it seems that it doesn't work with animations...
if i load an img sequence it just render the first frame!

Can you use PS's macro tools to process all the frames?
