Atl6.5: No smoothing for specular highlights from Sun and Lights.

Tue 12 Sep 2017 15:55

This Bug is still not solved in V7.0...

In Artlantis 6.5 the specular reflections from sun and/or lightsources are not smooth even if surface smoothing is set to max.
Look at the examples:

Hello,
Strange, I cannot reproduce...
Could you please, attach your test file (as zipped archive ATLA).
Thanks,

Hello Camille

Here is a very simple Testfile with a sphere and a torus. Sunlight and one red Light.
The highlights are not smoothed correctly, if the surfaces are smoothed.
The atla (6.5/ 6.5.2.12) file is attached.
Thank you for testing and hopefully resolving this problem.

The lower the glossyness of the material, the better the effect is visible.
Another example with glossiness set to minimum:

Hello,
I have downloaded the file, but it is missing the tif, sphere, taurus and the red light... Could you attach an atla, this way I would have exactly the same file as you have.

I have reproduced the problem, don't bother sending a new file !
I will enter a bug and let you know if it can be fixed.
