Tiles Rendering through VRay Camera - Gamma

Deadline
1

Just a quick one - I have noticed that if a tiles job is submitted from a VRay camera (no VFB or Elements) the gamma setup is not respected for the tiles, but this is not the case with the same scene and a normal camera. Exposure setup is not camera specific, but VRay Photographic.

When you submit the tile rendering job, do you have a pixel padding with a value greater than 0? There is a note in our code about potential gamma issues when the pixel padding is > 0 and I’m just curious if this could be related.

Cheers,

will test. thanks Ryan.

Ryan, yes it looks like it is related. Currently the same whichever camera type you use. Gamma issues with anything > 0 pixel padding.

Thanks.

Thanks for confirming. This is a known issue that we haven’t found a solution for yet. Is using pixel padding of 0 a solution you can use for now?

Yes, it is.

Is anyone able to write a quick Sanity check for Tiles = on but Pixel Padding >0 with a fix to reset?

Sanity Check Function:

		fn CheckForTilePadding =
		(
			(not SMTDSettings.TilesRendering) or (SMTDSettings.TilesPadding == 0) 
		)

Repair Function:

	fn FixTilePadding =
	(
		SMTDSettings.TilesPadding = 0
		setIniSetting SMTDPaths.InIFile "TilesRendering"  "TilesPadding" ( SMTDSettings.TilesPadding as string)
		SMTD_SanityCheck_errorReportRollout.log_action "Fixed" (color 0 155 0) true "Tiles Pixel Padding set to 0"
	)

Sanity Check Definition:

	#(SMTD_Private_SanityCheckFunctions.CheckForTilePadding , #fix, "Tile Rendering is enabled and Tiles Pixel Padding > 0!", SMTD_Private_RepairFunctions.FixTilePadding, true)

Hope that helps!

You superstar. Thank you.
