Title: low res bitmaps in render
Post by: maru on 2012-10-19, 21:21:29

Here is an example of what I've just experienced. One screen is from max's viewport, one from Corona's VFB, texture is a 1024x1024 JPEG, it's not very high res, but something's wrong as it looks much better in viewport than in final render.

update: changed texture's "blur" parameter in mat ed from 1,0 to 0,01 and it looks fine now. WTF?

Yes, this is a known bug, but we struggle to find a scene that reproduces it... Any chance you could share the scene? :)

Yeah, I'm blaming this one on 3dsmax API documentation, or lack of thereof. They give no clue about how to implement some stuff so default bitmaps would display reasonably :/

I noticed this bug as well, and it happens in all scenes i have. I need to manually change the bitmap blur parameter from default 1,0 to 0,01 to make textures look sharp.

It's gonna be most probably scene scale or model scale values or xForm related :) Once bidir is finished, we will take a look into it ;)

Maybe it's because I'm working in centimeters?

So am i, yet i encounter this very rarely :) Any chance you could try resetting xform? :)

Resetted xform, changed UVW parameters, added UVW Xform (not even sure what it does) and nothing happens, same blurry bitmap.
