Fatal error

[cadjockey]

Hi all,

 

I'm just starting out with viz using mental ray as the renderer.

 

I am pleased with the results I am getting with just little tweaking. I am excited to know that future projects will get better and better.

 

I have however hit a problem.

 

I was playing around with a scene and it's settings. The camera is an exterior and uses the daylight system to light it with mrSun, skylight and mrPhysicalsky.

 

I was getting ok results until I decided to try a shader. I didn't like the result so I removed it. Now every time I try to render the scene it suffers a fatal error and shuts down viz altogether.

 

The error meesage I get from MR is :

 

"max_base_blinnillumination"called mi_sample_light with unknown light tag 0x727

 

It seems to be only this scene that has the problem. I am able to render other scences no problem.

 

Does anyone know what I have done and how I can rectify the problem?

 

Thanks

i don`t know. maybe try to delete en setup the lights again.

 

where did you put the light shader?

I seem to remember having a similar problem a while back, in the end I ended up mergering everything out of the scene except the object with the offending material.

Hi guys,

 

Thanks for the reply.

 

I think I fixed the problem. I changed the sky to mrsky instead of skylight.

 

It rendered fine after this.

 

The more I learn about this software the more I realise what I do not know.
