Anyone have or had the problem of when trying to load in the FuseMerge tool your Fusion 8 program just closes without any warning? My co-worker had a previous build and the FuseMerge loaded in fine, but when he recently upgraded to the newest fusion 8 build, which I believe I have as well (version 8.2.1 build 6) his program started crashing too when he would load the FuseMerge tool in. Any help or information would be so much appreciated.

Thanks,
Judd Albrecht

For reference, the Fuse is located here:

Verified that it crashes my Fusion, also. v8.2b2

Why are you even using FuseMerge? My understanding is that it's intended merely to be instructive for Fuse building, not a production tool. It doesn't offer anything that Merge itself doesn't do.

edit: Solved it. Comment out line 110: self:CloneInput(InBlend, "BlendClone", {})

Thanks for the reply! I have found that using the FuseMerge in key areas speeds up rendering quite a bit. Does fusion use OpenCL to render Fuses? Like FuseBlur and FuseMerge? I only know fusion on surface level.

There's no OpenCL in FuseMerge. It surprises me that it would be faster than the native Merge. I'll have to run some tests on that to prove it to myself.

As far as I am aware, there are only a couple of the cloned tools that use OpenCL—the FastNoiseFuse does, and there's an OCL BrightnessContrast that serves as an example. I haven't opened up all of them to see what's inside, though, so I couldn't say for certain which ones do or don't.

Yeah, that would be great if you could do a test to see I the FuseMerge does render faster. I might have been thinking about the clMergeFuse, does that render with Opencl?

Thanks,

Judd

My test shows that the standard Merge and the FuseMerge are within 3% of one another for speed. Rendering a 1000-frame sequence from two HD plates took 18 minutes, 47.68 seconds with a Merge and 19 minutes, 17.19 seconds with the FuseMerge.

That's only a single trial, of course.

I don't have a clMergeFuse in my install, and I didn't find it in a Google search, so I couldn't look at or test that. If you have it on hand, could you please post it here? Just open it in a plain text editor such as Notepad++ and paste it here between Code tags. Or if Monday comes around and I'm back at work, I can hope to remember this conversation and email it to myself.

I guess that's not too much faster:) I usually replaced the normal merges that were bogging down during a render with the FuseMerge. I'm on vacation next week, but I will post the clmergefuse text when I get back in the office. Do you have Fusion 8? How did you get the FuseMerge to load in without the program crashing? Unless you have an earlier build where it didn't crash yet.

Did you miss the solution in my initial post? Comment out line 110. All it was supposed to do was make the BlendClone control, which puts the Blend on the main controls page without disabling the one in the Common Controls page. It is, admittedly, a little inconvenient, but removing it doesn't break the functionality of the tool in any way.

Sorry missed it:) Thanks!

The release notes for Fusion 9 include a line that they've fixed the CloneInput() method. I haven't tested it, but that might have fixed this problem.
