Color in viewport vs render...

Deprecated Genome Discussion
1

I was trying to double check the results of a “ToCamera” but I was getting some odd results. Not sure if this is Genome or just the way max works… If it’s the latter, then there might be a need to put this into the FAQ, as it means that the vertex colors might not be terribly useful for debugging.

I couldn’t double check the results in the debugger, since that’s still not working for me.

But the colors in the viewport are inverted compared to what they are in the render.

If I clamp the colors, it’s fine, but scaling it (by a positive amount) is not.

The viewport seems to do weird stuff when your vertex colors are not in the [0,1] range. I noticed that negative numbers or larger positive numbers made the viewport appear to use some sort of modulo effect on the displayed color. I assume its running afoul of something like this: color = (int)(uvw[0].x * 255.f) & 0xFF;

The summary of my story is that Max is weird and I didn’t do it.

We should figure that out.
Is it crashing? Is it coming up empty? Is it coming up with an ERROR displayed in it?
Please explain, we have a very short time to fix this :slight_smile:

Ok. Max 2012 sp2

If I have the Debug window open, and change the wiring of a the flow, add a node, hit Update, etc., then I get this…

MAXScript Garbage Collection Error

An unknown error occurred while MAXScript was
performing garbage collection.
If you get this error multiple times, recommend restarting max

OK

And then after that it’s a continuous series of…

MAXScript Rollout Handler Exception

– Unknown system exception

OK

And it points me to Genome_Magmaflow.ms…

fn prepareDepotForDragAndDrop = ( if MagmaFlowSettings.DepotPlacement == #off do return false for i = 1 to DepotNodes.count do ( hc.activeNode = editorNodeCount+i DepotNodes[i][4] = hc.activeNodePos ) )

And if I manage to close the Debug window, I get…

MAXScript Garbage Collection Error

An unknown error occurred while MAXScript was
performing garbage collection.
If you get this error multiple times, recommend restarting max

OK

I get this if I start max, make a Box, add Genome, and load the Bend preset then hit Debug.

And if I try to open one of the autobackups where I had the Debug window open, I get this…

MAXScript Garbage Collection Error

An unknown error occurred while MAXScript was
performing garbage collection.
If you get this error multiple times, recommend restarting max

OK

And nothing happens when I hit Open Magma Editor.

Out if curiosity, what is your

heapSize

Also, can you open the Genome_MagmaFlow.ms, locate the line

gc light:true

and remark it, then save the file.

I am not getting the Unknown System Exception, but I have seen the GC warning.

heapsize = 34603008L

gc light:true

Found one, commented out, saved, restarted, made box, added genome bend preset, opened editor, turned on debug, hit update…

I am not sure what to do about this, but we will try to figure it out. I wish I could reproduce this here, but I have never seen it.
Will install on my laptop and try there…
