When I render my scenes, the frames seem dark for some reason. Is it possible to increase the brightness of my rendered frames? 

Virtual CRASH 4 users can increase a scene's ambient lighting as of the April 1, 2018 update. See Chapter 20 of the User's Guide to learn more.

If you are a Virtual CRASH 3 user, it is possible to increase the ambient lighting of your scene by modifying the shader file “default.shd”. Before continuing on, first see the Blog post: to learn how to access the shader file and make customizations. This post also includes tips for creating a nighttime sky. 

With your favorite text editor, open default.shd, and increase the values for AMBIENT.

Rendering our scene in Direct Light with these default values, we obtain the following:

Changing the AMBIENT values from 0.2, 0.2, 0.2 to 0.5, 0.5, 0.5 as shown below:

results in the following:

Further increasing to 1.0, 1.0, 1.0, we obtain:

For 2.0, 2.0, 2.0, we obtain:

Finally, for 5.0, 5.0, 5.0, we have:

We can also reduce the value lower than 0.2. For 0.0, 0.0, 0.0, we have:
