There is a workaround for everyone who wants to avoid the bug. You can connect via madVR HTPC to the envy the 256^3 upload works without to desaturated colors. The only downside is that you lose 1D LUT functionality of the Envy. Steve check the report from Mathias I hope you fix that.

We have now been provided additional information from madVR, and the LUT format and structure used by Envy is more different than had been initially defined.
With the additional information we can now alter ColourSpace as required.
This is why I repeatedly said to test madVR HTPC, as 256^3 LUTs work perfectly, and based on the provided information for Envy, that should have been the same.
It is not.

Steve A new update has been released on MadVR Envy.

A ColourSpace Update is necessary such as the the madvr DLL

BlackJoker
ok but where do I find it?

It will be posted in this forum, in the thread on ColourSpace updates. When it's ready.

It has been unfortunate that Envy has had these bugs, but Mathias has isolated all the issues now, and the next ColourSpace release will have the final fix added.
Hopefully that will be this week, but we are in the middle of some other fairly serious development work.
As Fabio has now said, and as I have said all along, madVR HTPC works correctly.

Steve

I can confirm that the fix that is coming with 1.0.1.2251 is working the Upload function works correct now thanks - and your welcome

There's a new issue now. I've uploaded a "real" LUT (previously I only tested with a Unity LUT, which also didn't work correctly). With the color-corrected LUT I'm now seeing a pink border and noticeable color distortions. This does not happen when using madVR HTPC with the same LUT.

The I guess you need to talk to madVR...

Steve

so is it better to wait or try to load 3dlut? is the madvr dll included with 2251?

The dll is included in the latest release but it introduced other issues see my post above or in the avs thread where you can see my pictures.

There is a fundamental difference with madVR HTPC and Envy.
Envy can use LUTs in Legal/Video or Full/Data range.
HTPC can only work with Legal/Video range.

Steve

Mathias has reported not being able to replicate the issue...

Steve

Talk to him again he can replicate it and there is something really strange. The problem can be fixed when you create the LUT in ColourSpace export it import back in ColourSpace and upload it to Envy WTF. That makes no sense to me.
