Bump (bitmap filtering) + glossiness = problem :P

[tiagodmed]

I was testing rendering fabrics and came across the following problem ...
I adjusted the fabric material of my testing in a "frame" (close up frame... :P I do not know if this is the correct term, in Portuguese would be "enquadramento"). I adjusted the scale of the texture, bump intensity, glossiness ... And for that "frame" the yield was good.
But when I put the scene late in the "frame", which is further away, the yield had problems (I'd better show than describe, my English is not very good).

Blur 0,5 filtering Summed Area

Can you upload me the scene with the problematic camera (http://corona-renderer.com/upload/)? I suspect this was already fixed in the daily builds

I also have problem with bump filtering with the latest legacy daily build, i tried all the  modes even the No flitering blur is making my bump incorrect, i really hope it will be fixed soon...

I was cleaning the file to send and I open the material on the slate, only then realized that the bump texture was different from other (blur filter 0.01 and the others 0,5). I'll send this file anyway. But I will also send a corrected, now I did tests with variations in the blur filter (1 - 0,5 - 0,1 - 0,01).
In the background material appearing a strange effect, some "marked" areas.

Yes, I also encountered the same problem.
Now bump normally works only with parameters: blur = 1, the amount of bump no more than 1, sorrowfully (((

Yes i have the same weird effect, i've turned off bump for a wood floor because of  in a project...

I tested more and found that even with the bump parameters blur = 1 amount = 1 does not always work correctly!

Hope to see it fixed soon

This problem can be solved. Need to adjust the amount of bumps together with the blurring, ie less blur, the less the amount of the bump.
At least I got it. Try it.

i've already tried it but i see some weird spots
i will post a scene test that i've done a very simple one.

Here's my example :

Ca you post this scene?

Maybe because it is not correct to use a simple color like environment. I just put in the env.slot HDRI image. :)

Max12 please?
