Why are all the pictures I render with vr a little gray?

The analysis reasons are as follows:

First, there is something wrong with the optical network, shoot the lights. The optical network is too big, so give it a small and thin one, and the given parameters are too high, and the lights will explode.

Second, there is a main light source (VR movie lamp) in the scene. This lamp is gray when it bursts, and there is no hierarchy.

Suggestion: make a smaller optical network, and then make up the extra small pieces of light in each optical network and connect the spotlights.

Third, adjust the exposure mode, generally using the index, so that there will not be too many places exposed, and the light sense of the picture will be more layered.

Fourthly, to use photon mapping+light buffer mode, it is best to change the light buffer to a little larger, 800- 1000 (drawing parameters).

Fifth, lighting must be arranged according to the real light source, and a little light can be poured when necessary.

Sixth, the lighting must be bright and dark, with cold and warm contrast. The whole picture will look layered, not gray, and it is very durable.
