Linear Workflow to Backburner problem

guys pa help naman sa mga lwf to backburner na users dito. nung natapos na ung rendering sa backburner naging washed out ang image ko?



settings ko:

colormapping : linear multiply / 1.0 / 1.0 / 2.2



preferences ko:

gamma: 2.2

materials and colors: both checked

bitmap files: input- 2.2 / output / 1.0



any help would be appreciated, thanks guys

Eh paano kasi, times two ang gamma mo. Gamma 2.2 ka na sa Color Mapping, Gamma 2.2 pa rin ang Output preference mo...

yung output sa preference sir gawin mong 1.0 ...

BTW, that value of "2" in the input and output is bad omen. While it's OK to adjust the input value - the correct one is 2.2. Not "2" This will give you conflicts because you are using a general pref of Gamma 2.2 tapos iyong textures mo pinababasa mo nang mas madilim...

oh god, its such a mistake mga sirs... dahil ba sa pagmamadali? or kawalan ng pagasa? my input is 2.2 and output is 1.0



yan po ang settings ko sa preference... sorry my bad, but still washed out pa din po ang image output?



i tried to override 2 times para makita ang differences, isang 1.0 and 2.2 but still washed out, sobrang washed out ang sa 2.2



lapit na deadline ko.. hehehe.. sana matulungan nyo ko mga masters and sirs... thanks in advance...

Wag mo na sir baguhin ung gamma mo sa color mapping...! 1.0 lang... render ouput file... change gamma override to 2.2... that's what im doing... ok naman ung images ko...! hope it helps... just a try...! ;o)

i see you're using linear.. baka ito makatulong... http://www.vrayguide.com/2010/11/lwf-linear-vs-exponential/

may explanation si alex diyan.. if you're using linear set gamma 1.0 sa color mapping and adjust the curve color correction in VFB (see the video on the link). Save the rendered image in Openexr.

Sa tingin ko bakit washout iyan dahil sa color mapping mo na linear at na save mo as png., bmp. or jpeg... when using linear, sabi ni alex save it as openexr.

mga sir isama ko nalang po ito sa thread na ito about sa LWF when saving it.. dati kasi when im render a LWF output i save it as exr.. tapos nung napanuod ko isang tuts sa everchuchu, he save his file as tif but his colormapping Gamma is at 2.2. when i compared the images on the photoshop's actual pixel, mas litaw ang detail sa tif compared sa exr.. still a question to me when saving a LWF..

Every time I'm having problems with Vray, lalo yung mga weird na problema, I reset it by setting my renderer to scanline and then back to Vray again. Kung lahat ng advice dito na-try mo na dude, try mo lang i-reset ang vray mo. Let me know kung makatulong.

wow nice comparison master. anong format yung exr (16bit/channel, 32bit/channel or 32integer)?. baka 16bit/channel nagamit. Mas maganda nga ang compression niya sa exr16bit. Ill check later. Anyways very handy and thanks sa info.

Are you setting PS to 16bits?

Remember that exr's are floating point datas. Photoshop isn't really a good choice to manipulate it.

@RQUI. When using openexr, it is better to use AE in post processing than photoshop.. photoshop is not good in handling openexr IMO as I read some articles found in the web....

rerendered the image because i forgot if i save it as 32bit full float but the result is still the same... mas malinaw parin ang tif.. i dont know if it's because i used hdri.

if you're right sir mokong i think i need to go back with AE..

Tama ka tol. ganun din lumabas sa ps sakin kahit nasave sa exr32bit. Mas compress padin sa tiff compared sa exr32bit. Sa PS na siguro. Ok naman sa AE. Pareho naman Adobe bakit kaya?

Glad na point out mo. Hindi ko din napansin.

oo nga sir ngayon ko lang din napansin... im still experimenting..hehe try ko irender with different settings to make sure.. baka kasi sa hdri ko ang problema.. with exr kasi nagiging mas glossy ang mga materials ko.. post ko uli result mamaya..

salamat sa discussion but... as i was saying, straight from Backburner dapat ang result ha? i dont encounter problems when saving directly via VFB....



pag sa VFB ok ang result, pag sa Backburner washed out... i wonder why, parang na doulbe gamma sya....





@ mokong, i tried the link, but failed pa din?..



@ torvicz - will do your suggestion...



@ rqui - have you tried backburner?

Guys, maesterErick's problem is like this:

--When he MANUALLY saves from the VFB box, he likes the output coz he doesn't tick the sRGB button (no washouts)..

--When he SAVES TO FILE/AUTOMATIC SAVES in afterburner, output is washed out, even if he overrides the output file into 1.0..

What he wants:
He wants the save to file/autosave output to look like his manual save from VFB sRGB button unticked output..

Tama ba maesterErick?..

Sir tama si Boss Cloud.

Kung ang problema niyo sir ay exposure lang then okay lang ioutput yan kahit siguro overexposed. Use exr nalang 32bit full float. Then tone back the exposure in photoshop. In case, you use color corrections sa VFB, pwedeng imimic niyo nalang yung settings from VFB to photoshop (example kung gumamit ka ng color curves sa VFB then pwede mong gayanin yun using curves adjustment layer sa photoshop).

Yung backburner ata ay ginagamit niya yung mismong sa max buffer window so hindi niya katulad yung output sa VFB.

Hope it helps...

@ ymhon - thanks for the time to share your knowledge, but im still holding on to master julcab's workflow, which is like mine... still waiting for him to answer.... thanks dude

Send me a stripped down file Erick and Ill look at your file. But before that.

1. What happens if you use (only) your own workstation as a rendering server via backburner?
2. What happens if you save into a different file format such as tiff or targa.
3. Are you saving 16 bits exrs?

Try this go on each machine, open max and set the gamma to 2.2 then save it.
or try adding this to the CurrentDefaults.ini file on your renderfarm machines..

[gamma]
LoadEnableState=1
CorrectColorPickerState=1
CorrectMtlEditorState=1
InputGamma=2.200000
OutputGamma=2.200000
LUTFileName=


and make sure your using the same system like 32bit or 64bit.

hope it help.

thanks for your share guys, i finally got it!!! whew...

How？

@ itay vertex - Just ticked the "Don't affect colors (adaptation only)" button



and "use system default gamma" when saving it....



i think i learned it sa link na binigay ni mokong, naenlighten ako dun...

binasa ko ng paulit ulit hanggang sa natorete na utak ko at halos makabisado ko na at maintindihan ko eventually ung sinasabi nya



thanks dude mokong... big help for me



now, im a LWF user na... hihihi...
