[Radiance-general] Preview error - unknown object type "ashik2"

[Greg Ward]

The 'unknown object type' error is caused by reading in a frozen octree (generated with "oconv -f") on an older version of Radiance, before this type was added.  You need to update your copy of Radiance from https://github.com/NREL/Radiance/releases

Chris has the right advice on X11.

Cheers,
-Greg

> Hello,
> 
> please I need help. Whenever I run objpict or objview or rvu, I get the same warning each and every time:
> rpict (or rvu accordingly): warning - unknown object type "ashik2"  
> This error repeats no matter what I try to preview, a simple chair or a more complex model.
> The preview than is/is not produced - I was not able to identify the trigger.
> 
> I am new to Radiance (and Linux). I got aware of this problem since I reinstalled Radiance from the NREL Radiance releases (I did this because I realised I was missing some files). 
> 
> If I do understand it well, ashik2 should be an anisotropic BRDF model, describing the appearance of a material, and it is a calculation model - so "something built in".
> 
> Please, how do I fix the problem? Can please someone explain what went wrong? 
> 
> I also get an X11 error. 
> XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
> 
> This was already once discussed on the mailing list, but was not somehow resolved. I have tried to upgrade the graphic card driver, but with no impact. Please, did someone solve this?
