If I have an object in three.js which has a texture applied to it (a colourful texture), for example a car - how can I add a partial reflection to the surface, so that the final material is say, the combination of a shiny red metal and the reflection of the scene?
I am familiar with creating reflections using an additional camera and cube mapping, but I am not sure how to combine this with an objects existing material.
An example of the reflection method I am using can be found here:
If it is possible to combine the materials, is it possible to control the opacity of each part (the original material vs the reflection) to control how 'reflective' a surface is?
Many thanks
