Value Ramp/Fade Issues

[robbiet]

Hey guys. Just wondering if this is a bug or I have a setting wrong somewhere...

So I was trying to get a long gradual ramp from one color to another using color wash...maybe over 10 seconds. However, when I apply the effect it is doing a full ramp every couple seconds. I did verify that I have cycles set to one. I’m seeing similar issues with other effects when it comes to fades or if I apply a value curve. They don’t seem to be spread uniformly over the expected time frame.  Hope this makes sense. Kind of tricky to explain.

Sorry. Just noticed we should not post here.

Click on the effect in the grid and do a control-c copy.  Then paste it here.

This board is fine.  It's a child board that is listed as deprecated.

Ok. Thanks. Computer at home. Will post later.

OK.  Here is the white>red color wash.  Should fade to red over 10 seconds but is actually changing to red every 2.5 seconds (4 times in 10 seconds).

Only thing I see that is abnormal is you have the Brightness set to 400%.  I'd put that back down to 100% but I'm doubtful that alone fixes the issue.

[robbiet]

Ok. I’ll try that and see if anything changes. Thanks.

So FYI, setting the brightness back to 100% fixed this issue.

Cool thanks for reporting back.  Its amazing sometimes we spent many minutes or hours trying to figure out why something isn't working then just seeing the actual XML for the effect and its solved in a few seconds.  Just a couple days ago I had someone saying he couldn't get an effect to show up.  He did all these strange steps and said he finally fixed the problem but to us we knew it had to be something else wrong.  I finally said copy and paste your effect to us and within 5 seconds I noticed this exact same parameter, Brightness, was set to 0%.

Maybe we should have warnings in Check Sequence for effects with brightness = 0 or > 100.

[robbiet]

No problem. Glad to help.  I did see the other post regarding the brightness slider. Maybe something goofy going on with it. At least for my issue I thought it was interesting that the effect was happening 4X when the brightness was set at 400%. Maybe something in the code getting multiplied by the brightness?  No idea. Just speculation.

Yeah the color values are being multiplied by the brightness and then clamped to 255.  I'm sure if we saw graphs of how each color changed across the ramp and then imagined each color shifted up and clamped it would be obvious.
