Title: Blur parameter: strange and odd behaviour!
Post by: cecofuli on 2013-05-06, 23:40:43

Hi,
as many users wrote, there is something strange in the Blur parameter in the texture rollout. I don't understand why I have to change this value from 1 to 0.1 or.. 0.01!
I have found that the higher the resolution of the texture is, the lower must be the blur parameter.
Now I'm working with a wood texture 10.000x10.000px  and I've to use blur value as 0.01! This for every channel!
Otherwise, the shader is too blurry and smooth.
I want this: with blur 1.0 my textures (1k, 2K or 10K) must to be correct.
It's so waste time try to check the correct value for every blur parameters.

What's the solution?

I long ago noticed this problem: for large textures must-set minimum blur(0,001).

I cannot upload my scene, cause texture NDA. but just create a box, apply an high-res texture and play with blur option. That's all.
The box texture is about 7000x3000px

Now the problem will be  that I'll have to change all the blur setting about 0.01 with the new fixed build.
When I'll open the same scene, the blur value will be incorrect (too low)

Keymaster, I know, you have million stuff to do, but, can you solve this problem?
Now I'm working with OFFICIAL alpha4, but I need IES for our next project.

Thanks

I'm working with A4 and the problem is still here =(

Fixed. The problem was caused by the texture being huge in only one direction. I would appreciate testing, as I am not sure the fix will work everywhere and other scenes won't break.

I'll look into that shortly. I am also making a legacy build, but Chakib, you should really upgrade your hardware :D
