Redshift Quick Tip: Fix Glass Refractions

In this Redshift Quick Tip, Liam goes over how to get proper refractions out of transparent, refractive objects. The key is adjusting the default trace depths in the Redshift Render Settings.
** Please note, from the RS Manual: "Separating the controls like this provides more flexibility, allowing individual effects to be rendered with increased depth when needed but restricting unnecessarily high render times. For example, let's say that reflection and refraction are both set to a value of 4, and combined is set to 6. If a ray had already been reflected 4 times, then it could only be refracted 2 more times because the combined trace depth is 6."

thanks for this video. It did what intended. Preventing a 3D artist from staying until 4 am

Awesome to have this answered! Theres definitely allot to know when it comes to the nuances of the Redshift render engine! Thanks.

Combined should equal the total of the reflection value and the refraction value. If combined is lower, it will clamp these values. Hope that makes sense and keep up the great work.

wooo Liam appearing in my feed again!

Transparency Depth is not limited by the Combined Depth parameter. You might also need to crank up reflections as well if you need those subtle internal reflections

Glad it was helpful!

This is great. While this is about adding quality, and thus raising render times, I dream though of one day seeing a Redshift tutorial about refraction that is showing how to speed up glass/liquid renders without a huge hit on quality..

Hi there, I'm wondering if you can help me to get alpha channel in redshift after apply subsurface scattering material or transmission with depth? Thank you,

Wait, so you mean I'm not supposed to fix it frame by frame manually in photoshop? Oooh....

Wow, such a simple and helpful tip! I've always struggled with glass in Redshift and could never figure out why I needed to crank it way beyond the number of bounces I needed. Turns out I just needed to add one more bounce. (btw how did you find out that it ignores the first bounce? I feel RS has so many little secrets that the docs don't describe)
