Hi all, list.
I have a few questions about MR and i was wondering if
you can give me some info.
1. When rendering with mrfm i`m getting this in the
output window:
"RCFG 0.3 warn 542002: angle between normal and
geometry normal more than 90 degrees."
What does it mean?
2. When rendering with mrfm i`m getting this in the
output window:
"MSG 0.n error 011105: cannot start thread X (where
X is a number): Not enough storage is available to
process this command."
???
3. In order for someone to store more than 10k
photons,
does he has to use a photon shader connected to the
appropriated light source?I`m getting an error in the
output window "cannot store more that 10000 photons(or
something like that).
When i use a photon shader,how can i alter the
raytraced shadows (since i have checked the suppresed
all maya shaders)?
Using shadow maps its not an option because it
produces not acceptable shadows.
4. Has anyone used a material photon shader(not a
light photon shader)? I havent seen so far any big
visual differences, when i pipe it to the material
shading group,rendering with glob illum and fg, while
using light photon shader and a "hdr-object-light" as
indirect light.
5. I`d like to hear your comments and suggestions
about rendering interior
scenes(bedrooms,cathedrals,etc)
I mean so far the "dome" trick attached to an hdr
image works preety well for outdoor scenes,but to my
knowledge its really hard to use the same technique
for indoor lighting situations. Right? Wrong?
6. Finaly, i`m looking for an "updated" book for
mental ray or mental ray for maya from an artistic
point of view and not a programmer.Is the "rendering
with mental ray, Second revised edition updated?
As a side note i have experienced some crashes with
mrfr,like most of you i think.For example if you reuse
your fg rays (unklick the FG Rebuild)sometimes mental
ray refuse to start.Down in the help line you can see
the translation prossess but right after that, the cpu
goes down to zero.
Even when i hit esc on keyboard, it doesnt aboard the
render process.I know its still an early version of mr
for maya,so hopefully in the next update/version of
maya,they will fix many issues/bugs.
Thats all for now.
Thanks in advance for all the answers you can give me
about these not so common problems,and sorry for my
English.
All the Best
-Dennis
