LWF Poll

First topic message reminder :

I am always curious about who use this technique, if you do not know what LWF means, please choose either answer #2 or #3.

maybe it's time the thread starter shed a f***kin light on this....

after reading the link from dude mushroom....yeah, I guess it's Lots of Work Flow nga...hehehe

I'll stick to "torvicz work flow" for now....

share mo naman ung TWF mo.... har har har...

I just go with my flow mga dude....hehehe...

pwede ring EWF (eric work flow) o kaya DWF (denz work flow) hahaha

sorry O.T. na...nagkakatuwaan lng po....

#3 din ako. i dont have idea about LWF.
id rather go for TWF Torvics Work Flow haha.
my idol in environment effects.

2 for me... ive read it.. but dont use it... and havent tried either.. a lot of work too...

i choose #3 ! sana makita natin yung pagkakaiba sa may LWF at wala
para ma inspire naman tayo!

Haha dami nag #3....dapat kasi nag post man lang ng brief description yung TS about this

well maybe if you asked a bit more politely....

there is also this thing little thing called Google.....

weird that it seems to be quite the opposite in the official vRay forums.



my intention when starting this thread was to see how many use this technique, nothing more nothing less. that was it. that was my only intention. i did not say i was going to explain it, i do not know why people here think that i "HAVE" to explain it. i am not trying to be rude here but i was under the impression that people who did not know it would simply find out using the internet and not wait for an explanation in this thread. i do not visit this forum everyday, actually i just came back from like a 2 year hiatus from the old 3D Pinoy.

anyway the link from mushroom is correct, but in vRay SP3 a lot of the manual steps to achieve LWF will be automated. but to be honest its really very easy to do, just set your gamma to 2.2 (1.8 for LCD) in MAX and also check the input bitmap parameters to use the same, use the vRay frame buffer, enable view in sRGB mode, save images using override gamma (you can set this automatically in MAX), get used to the adjusted gray and color scales for solid colors and that is it. but again for SP3 most of this will be automated.

now ask yourself this question, if this was such a "waste of my time" technique, i wonder why the CREATORS of vRay even bothered to put it in SP3 in the first place......

Perhaps it's the TS's responsibility to give details on his topic. We don't even have to be obliged into googling it.

It just happened that most of us here are not familiar with it. It's good though that you included option 3. But it's not enough specially when they start to ask that question. Anyways, thanks for clearing this matter up bro!

even so, i choose no. 3.

Lots of Work Flow - good one

i am predicting that in a year or two (or even less) you will be using LWF. , 7 years ago we had this debate about vray vs. Brazil, vray was still at beta 0.7 then. i was a vRay fanboy and you were a Brazil fanboy back then, and now you are in the vRay camp. when vray SP3 becomes the most widely used version of vRay, more and more people will use LWF and so will you

thank you for politely asking

many techniques, tricks, tweaks can be done to finish of a project, so that is not the best way to show how it works since there could have been a lot of Photoshop done on the image already. having a simple un-edited image is the best, no tweak, just two solid materials, a direct light and some sky (slightly blue). besides i do not have time to do 3 different renders from a single project using 3 different techniques.

NON-Linear Workflow using Linear color mapping, 1.0, 1.0, 1.0



NON-Linear Workflow using exponential color mapping, 1.0, 1.0, 1.0 (lights have been made brighter to simulate desired illumination equivalent to linear).



Linear Work Flow using Linear color mapping, 1.0, 1.0, 1.0



The 2 colored squares on the upper left were added in Photoshop. These represent the "true" paint colors used in the scene in terms of RGB values. These colors are actual bitmaps mapped onto the objects, not made in MAX using the diffuse colors.

The 1st image has accurate color, as with all linear color mapping scenes, but the light is too harsh and not enough bounced light in the shadows. Imagine if this was an interior scene with a small window, you get the point.

The 2nd image uses exponential color mapping, better lights in the shadows, less glare, etc. But the colors are going to get muted, and don't even go to vRay glass using exponential color mapping.

The 3rd image uses linear color mapping in a linear work flow (LWF). Notice the colors are true to the original paint and lighting is better, shadows are not too dark, also light will travel further inside a room for an interior scene. Also color bleeding is WAY better (try doing this in a white room with red carpet). Basically its the best of both worlds.

I know that you can achieve #3 using other non-linear means, like adjusting the RGB offset of the maps, darkening your textures in Photoshop, using vRay material wrapper, etc. If you are comfortable doing that I am not here to change you mind (or anyone else for that matter).

I simply started a poll.

LWF

Interesting stuff. Is this only available in Vray? How about MR?
