All I need to do is make sure that Auto Brightness is disabled, right?

Re: Max Brightness Value

Ok, I see, just opening the scene, shows a NaN value. @B.Y.O.B. is it an uninitialized variable ? Where does it come from as soon after having just opened the file ?

Re: How to imitate real world materials

I think your matte mix-in is reversed. Either switch the inputs or change the mix amount to 0.8. It looks correct to me :?: The section #3 could be avoided (for instance by using kd=0.6 instead of kd=0.8) but it would me hard to do in the case of glossy material and it is probably easier to read as...

Re: Max Brightness Value

It's just done it again. (Snip image attached). If you could just bear with me whilst I upload the whole project as our broadband connection is rubbish! The scene is not going to be very useful anyway if it is not something I can reproduce in a reasonable number of tries. When do you get the NaN va...

Re: How to imitate real world materials

From light measurements I know that the surface that I want to imitate in luxcorerender has an overall (integral) reflectivity of 60% in neutral white color. 40% are absorbed. This is the ratio for directional depencies of this 60% of reflection: 20% are matte (ideal lambertian diffuser) 40% are gl...

Yes I'm using glossy surfaces...so just to understand, should I switch any materials in the scene?

Re: Max Brightness Value

I've only had the NAN once. The scene I am working on is still very WIP and I'm adding more and more stuff to it, so there is a chance it will re-occur and as soon as it does I'll save a copy of it at that point for you. Unless of course there is anything else you would like me to do in the meantim...

I can't reproduce the issue.
Here too :?: Do you always get the NaN ? By just opening the scene and starting the rendering ?
