kitchen shot
Re: kitchen shot
tested on a new fresh scene, using soft 2012 x64bit SAP. Its not working unless i use sphere or cylinder. Yay more bugs

disc, object and rectangle area lights with physlight and blackbody.Maximus wrote:tested on a new fresh scene, using soft 2012 x64bit SAP. Its not working unless i use sphere or cylinder. Yay more bugs
this is si2012 sap, but i tested this also with si2012 and it works.
could you send me your clean testscene, so i can take a look?
Re: kitchen shot
switchin to point make it works but it gives a total weird output, like if the light is coming reversed, from the opposie side of the light itself..

ah, ok, now i see.Maximus wrote:here it is
you used a spotlight, that does not work. its the same like in vray, spotlights does not exist in real world as a lightsource. use pointlights for this and it should work.

also use a cone value of 0.5 for example.Maximus wrote:switchin to point make it works but it gives a total weird output, like if the light is coming reversed, from the opposie side of the light itself..
edit: also, you have to look on the z direction of the light, thats the light direction.

Re: kitchen shot
alright thanks for clarifing, now it works
Gotcha
Gotcha
Re: kitchen shot
the whole physical stuff needs to be implemented as presets and documented with some examplescenes so the users know that it exist and know how to use it, but yes, thats mr (integration).
Re: kitchen shot
@Kzin question for you, what is your opinion on buying MR standalone to be used with SI? It there any meaningful workaround that one can use? Will that give more freedom to user?

Re: kitchen shot
i dont know. from my knowledge (rendering with mental ray book), rendering with standalone means alot of command line commands.SreckoM wrote:@Kzin question for you, what is your opinion on buying MR standalone to be used with SI?

if you think about it to overcome the integration problems, you will need to write alot of custom commands in bat files.
this could end up of several a4 pages of text. you could download the mr demo und try it by yourself, but you have to know all the commands which you need to call the ibl light for example and replace lights or shaders. its possible, but i dont think one second to do this, because i know the examples from the mr book. ;)
and also keep in mind, if you output the ibl from xsi for example, it uses the xsi geo shader also in standalone with all the problems. so the best way here would be to output the mi without ibl and insert the ibl thru commands in bat files.
someone with experience in that could give a more detailed awnser. perhaps in the mi forum, most of them uses custom commands and renders with standalone.
Re: kitchen shot
There is absolutely no chance a user or someone experienced enough can put hands on this geoshader problem? why is it so complicated to fix?
I have 0 knowledge of code and such, just wondering if anyone could do or it must be AD only, and why?

Re: kitchen shot
from what i know, its the implementation of the shader in xsi, so the problem is xsi here.Maximus wrote:There is absolutely no chance a user or someone experienced enough can put hands on this geoshader problem? why is it so complicated to fix?

i dont know if this can be fixed, but i think you have to rewrite the geoshader?
perhaps its possible with a native geo shader of mr, if you get it in. will take a look in the mr shader, perhaps a simple base.mi append brings in the native one (if the native one is already in xsi, then you have to change the code for xsi).
Re: kitchen shot
Hi Maximus,
Just saw this and don't have time to go through all that was said in detail right now but here's a couple things:
I use triangle filter set at 2 for stills. I've not gotten good results with anything else. Also, I never use unified. I've tried many times but never been able to get decent render times out of it and I don't like the results (for stills anyway). I just set sampling contrast at .058 with min 0 and max 2.
One thing is that you have very intense DOF. To do that MR has to do extremely high sampling so it's going to take a long time. I think the DOF is WAY too shallow, as a photographer you would never shoot it like that (unless it was for some very specific reason). At least your main center of interest should be fully in focus. Go lighter on the DOF`
