Using Gamma 2.2, part 3

tags: tutorials, rendering, advanced


To change the gamma in which the renderer will work with it's enough to find drop-down tab named "V-Rray: Color mapping" in the "V-Ray" tab on the "Render Scene:" (F10) window, and set the value "Gamma:" to 2.2.

V-Ray Color Mapping Gamma Value

A feature of V-Ray renderer is that the color mapping gamma correction works in the V-Ray Frame buffer only, so if you want to see the results of your manipulation with gamma it is necessary to turn on frame buffer on "V-Ray: Frame buffer" in the "V-Ray" tab.

Great! I use this everyday. Stoppe in the frame buffer enabling, but generally great! Thanks!

there is any chance to get render elements with this settings?.bec..if frame buffer is on elements will not work..

Hi ajith,

The 3ds max duplicates the render elements to separate windows as rendering process ends when you render to a standard Frame Buffer.

But, when you render using V-Ray Frame Buffer, all chosen elements already are in the V-Ray Frame Buffer single window. They are available by the selecting in a drop-down list in the left upper corner. The RGB color is the default option. Just pick the needed render element from that list and save it just like you do it with the RGB color rendering by clicking floppy disc icon.

Hi ruls, the so called flying chairs effect is a result of an insufficient contrast of the shadows or too lightened shadows. It shows up mostly in well lit areas with small details that must cast shadows. Usually this flying effect arises because of the excessive brightness of an ambient lighting or, if you use V-Ray renderer, because of low quality setup of an Irradiance Map. To get rid off this shadowless effect, you need to lower the brightness of a filling/ additional lights and rise the setups of a secondary illumination, increasing the GI maps quality. Also, this like effect can appear if you have a incorrectly set gamma value of the input texture. For example, if the 3ds Max and V-Rays gamma value is 1.0 when the gamma of the input bitmaps gamma set as 2.2. Make sure that those gamma values both are identical. For this check if you setups of the gamma values correspond the ones in the final part of this tutorial.

i used to input 2.2 for the output gamma option aswell and everything was very bright and faded. now it is correct as i inut gamma 1.0 for the "output gamma" however , i think i still have a problem about texture baking as it ignores my settings thus over gamma-ing the autosaved image(the lightmap for example).to overcome this, i have to manually save the image by pressing the "floppy" icon in 3dsmax.

so atlast a real question to you:
as for the 3dsmax 2009 versions and above, is it still a good idea to use color correct plugin's gamma adjustment for defining the texture's gamma to 2.2 ?

Hi bora, there are known bugs in the autosaved rendering to texture images. Using manual saving is a preferred way.

We believe that using color correct plugin for local changing of a textures gamma value is a bad idea at all. This is a complex way and it is better to globally change the overall input gamma in the Gamma and LUT tab of the 3ds Max preferences.
