Usind HDRIs In Vray
-
can anyone please tell me how to use HDRIs when rendering a sketchup model in vray.....for instance, where do u insert the hdri, in the GI or the background??...and why do i get a black screen in the frame buffer when i do so?....and how do i control the size, distance and angle of the hdri???
...........somebody please help...... -
Most likely you are getting a black screen because you are using the physical camera along with the HDRI. You must either turn off camera, or turn up the multiplier on the HDRI. If you you are using the original release, the multiplier should be set to around 10000 if physical camera is on. If you are using SR1 or later, the multiplier should be between 5-10. HDRI can go in environment, background or reflection, or in all three depending on what you are going for. Don't forget when you use an HDRI in Vray, you must change the texture setting to environment and changing the horizontal rotation number will spin your HDR image until the sun in is in the right place.

HDRI in the GI will be the light source.
HDRI in the background will be, your background where there's no other geometry as well as in your reflections. -
