RayFire Tool


Mir was able to get hold of me last night (via the email sent from this forum) with my login and license info (Thanks Mir).

Sigh… But now I’m having a hard time downloading the install file from the RayFireStudios site. I don’t normally have problems downloading files but every time I try to download it gets to about 30mb to 45mb then the download dies. And this happens with or without a download manager and the download won’t resume when using the manager.

The filename has ’ ’ in the name such as ‘filename.zip’. Don’t know if that is a problem or not. Not sure why downloading should be such a problem.



Thanks to Mir and Anselm (and John), I now have RayFire downloaded, installed and functioning.

Thanks again!


I started using RF Cache feature recently and noticed an issue. The cache works fine with flat fragmented objects but when used rounded fragmented objects like a sphere it come out lumpy. Here is an example:

The top row is a sphere and a box fragmented. The bottom row has been RF Cached. As you can see the box looks fine but the sphere looks like something is wrong with the smoothing. I have tried to add smoothing modifiers to it and also tried the RayFire Cracks modifier to no avail. Anybody else have this issue? Does anybody have a solution? Thanks

Here is a closer look:


The issue is that the individual pieces (as objects or as elements) do not smooth between each other even when the same smoothing group is used. Smoothing groups only work between faces sharing an edge–so never work between elements or objects. I have a feeling that adding a Normal calculation into RF would be possible but slower to build the fragments.

I think it’s kind of a non-issue, though.

You should think of rendering the largest non-destructed set when possible. So use the original, non-fragmented ball in your render (and hide the fragments) until it collides and fragments–then hide the original and unhide the fragments. At that point, the lack of smoothing is really a non-issue because the fragments will go do their thing and they eye won’t see any adjacent faces with odd smoothing.

Another thing is that some motion blur can also hide the smoothing oddities in many situations.


Dear all,

I’ve been using Rayfire for a couple years for simulations, but have just used the Image Trace feature for the first time. I’m using it to create a custom shape for an island (shaped like a human) and I’m adding terrain features procedurally.

The Trace object works as promised, but Max keeps crashing. The projects take tens of minutes to open (with almost nothing in them), and it keeps getting hung up. I’ve been banging my head on this particular wall all day.

Any thoughts or recommendations? Thanks!

Rayfire 1.65 on Max 2015.


The issue has been FIXED in the new version(1.66) of Rayfire. Thanks Mir.

Well Rayfire had/has “Custom Vertex Normals, no smoothing artifacts at sliced edges.” The top row of my image the objects are fragmented and look smooth. The bottom row is the RF Cache. It is one object and that is why I tried smoothing groups. No need to hide or use the original object. Rayfire will smooth fragments in regular fragmented object and now in RF Cache.
