[Fuse] Grade

[ArtemHlezin]

Hi friends. I am not huge fan of mixing workflows/ideologies from different softwares, but for fun I wrote Grade fuse. Please note that gamma works not like in nuke. Be careful with combinations of negative gamma slider/pixel values (because of NaNs, INFs etc.).

Now that's a worthy submission for Reactor!
Well done! Thanks a lot.

Nice entrance, first post with an awesome tool ! Welcome to the forum Artem!

WSL is attracting some really quality first posts.

Regarding the NANs, in Lua you can test that by comparing to itself like

Code: Select all

if (p ~= p) then

and if false then set the value to (+/-) math.huge or some other suitably large value.

I'd love to try this out with CustomShader3D though... I have a tool in the ColorBundle3D but I was never happy with the GUI. You don't use the color wheels, but you have sliders that seem to make a lot of sense, especially for animation.

Thank you guys!
I am new to fusion and lua, so maybe some parts of code are not designed well. The biggest problem for me is the lack of online documentation.
If you have some issues, please let me know.

Chad, thanks for advise. It is really useful. Yours CustomShader3D is awesome - I have already bought it.

Terrific first post - welcome to the forum, @ArtemHlezin!

And great tip, too, Chad - thanks!

You can make a general purpose "NaN Flag" ViewShader with

Code: [Select all] [Expand/Collapse] [Download] (Untitled.cg)

1.         f.Color.rgba = isnan(f.Color.rgba) ? float4(65532.0, 0.0, 65532.0, 1.0) : f.Color.rgba ;
2.         f.Color.rgba = isinf(f.Color.rgba) ? float4(0.0, 65532.0, 65532.0, 1.0) : f.Color.rgba ;

EDIT: The Gain/Gamma sliders in the viewer process after the ViewShaders do, which is... interesting. In this case it lets you distinguish between "cyan" which might be in your image normally and "supercyan" which almost never is.
