Maxwell Render caustics

I decided to do a test of Maxwell Render casutics after reading some time ago an article of Bertrand Benoit about it. I will not explain the differences between Maxwell Render and Vray because Bertrand has explained it very well. only one thing, Maxwell Render is an unbiased render engine, therefore the caustics are done automatically.

For the test i used three glasses with a glass material with dispersion. If you want to download the glasses, click link below, the file is an obj format.

  1. The renders looks great. I’m just getting started with VrayForC4D. I hope to be able to get similarly photorealistic results with that tool. Thanks for the .objs! I really enjoy your posts…

    • Shalom Ormsby, thanks for your words, I hope to see your work with vrayforc4D, is a good tool, you can also get very good results with vray.

  2. Dear Mr. Fresnedo

    I am writing to request permission to reproduce part of your image of glass in an academic paper on the perceptual analysis of image shading. I have attached a copy of the caption that cites your work.

    I have spent considerable time trying to create believable clear glass using the Finalrender and Vray renderers, but I have not been satisfied with the results, probably because I do not have sufficient skill to set up the appropriate scene and material parameters. Your glass is the best I have seen on the web, and I would like to highlight it in the paper I am writing.

    Thank you for your consideration.

    Figure 8 – Example images of different 3D shapes with different material properties and different inhomogeneous illuminations. The depicted materials include translucent wax, hammered copper, glossy red paint, glass, four different types of cloth and blue fur. The glass example was created by Toni Fresnedo ( using the Maxwell renderer. The cloth examples are from Sadeghi et al (2013) using a new state-of-the-art algorithm for simulating cloth materials. All of the cloth examples have the same depicted geometry and the same illumination, but they have different BRDFs, which produce noticeably different patterns of shading. All of the other examples were created using the VRAY renderer.

    • Hello Mr. todd

      Yes, of course, you can use the image for whatever you need. It is a pleasure for me.

      Thanks for your interest.
