[micvan]

Hi,
sorry for my english but I don't speak or write very well ( I' m italian) so...
I've a problem whit emissive material in V-ray because for see the emissive light in render i set parameters to 50000 and the light is only white but if I would have a light red or yellow?
Thank's

Re: Emissive material

read the manual, dudissimo ! : : : :
just change the color next to the intensity setting panel

Re: Emissive material

I understand,
but if I change the color in panel, the set 50000 emissive is too high to see, for example, the light red or green and if I push down the parameter i don't see the light in the scene ...

Re: Emissive material

The physical camera is enabled, which will throw off the scale of emmissive materials. So even though you think that those numbers are high, when using the physical camera they really aren't. For more info, search the forum for physical camera, or look through the manual.

Re: Emissive material

for semplicity post an example...
the first image is the set of emissive material whit physical camera enabled and the second image is result, so i set the emissive high and result is good but i don't change the color of lights so I turn off the physical camera but the render is only whit, why?

there is no map an no option but the intensity and the color in the emissive layer.
I think you really should read the manual... :

I hope it was helpfull

Re: Emissive material

ok,
I've find the solution. I've turn down the trasparency and I see the light colored in render but in the window preview the ball of the material, whit intensity 15000 (example), is always white but it's not a problem.
But there is a manual in the site? Because I've the manual: sketchup for vray...
