VRAY Light issue

[shamrez123]

Hey guys I am have some serious lighting issues! When I put a spot light or IES light it wont show till I put the intensity to a minimum of 100,000! Even with 100,000 it is barely visible! Also the IES light I put does not show the light source, it just shines. If someone could help me it would be awesome I am trying my best to have awesome night renders! Aside from that VRAY is an excellent program.

This can happen when you are trying to use a very dim light and your camera settings are not correct. Try adjusting your camera exposure to something lower like a shutter speed of 30 or 60 and an f-Stop of 2 or 3 (making a brighter image), and then adjust accordingly.

If you take a picture in a dark room you need to either adjust your exposure or add more light. In your case, I would adjust your exposure since your IES lighting profile is accurately depicting the shape and intensity of the bulb it is emulating.

Thanks for the reply! I will give these settings you suggested a shot and I will get back to you with the outcome! Thanks again

Hey so I gave the settings a shot and its much better, thank you! Just some of the areas of scene are much darker than others while using the IES lights for some reason (exterior rendering) I am hoping I can fix this while playing with the camera setting.

It's going to be a mix of both lighting placement and camera exposure. In most cases you have to approach lighting your scene like an architectural photographer would in the real world. Acurate lighting may actually produce under exposed areas in the rendering and you can fix that in one of two ways. First, by changing the lighting design. It could be you just need more light in or around the space. Next, if design is set and you dont want to change it, you may need additional fill-lights to add needed light to a dark space. A quick Google search for "lighting for architectural photography" will bring up numerous real world tutorials that also apply in your digital model.

Hope that was helpful! Let me know if you have any additional questions, I would be happy to answer them.
