Indigo 2.2.6

[fused]

@Whaat:
i just called it "Absorption Layer"

"Surface Color" is a way more user friendly name

[Whaat]

@Whaat:

Whaaaaaaaat!?!?!? :O these are amazing!

heh...are u joking? It's just simple application of the new absorption layer transmittance feature....(man..I hate typing that parameter) Try it out in the 2.2.6 mat editor.

Great...I have one vote for 'Surface Color'! Can I have another? Three votes will over-rule Ono and Ben! ;) haha

You would be amazed how much beauty can exist in simple things... ;)

As far as simple names go, 'surface colour' is good, I think.

I'll look into the EXR issues and report back soon.

[juan_irender]

so blackbody base_emission works but rgb doesnt?

Exponent = 1 works exponent=2.2 doesn't it seems

Yes, Pixie! If you use an exponent of 1 with an EXR texture on the emission channel, Indigo doesn´t crash, I can confirm too.

Thanks for this release, Ono! The UI of Indigo is very responsive now, I like the new Light Layer Blending panel.

I'm with the 64build.

Maybe Cindigo is the evil here, but I don't think so... in fused we trust ^^
Anyway I just paste here a generated material that crashes Indigo:

Code: Select all

    <material>
        <name>EnvMap_mid4</name>
        <diffuse>
            <albedo>
                <constant>
                    <rgb>
                        <rgb>0.000000 0.000000 0.000000</rgb>
                        <gamma>2.200000</gamma>
                    </rgb>
                </constant>
            </albedo>
            <base_emission>
                <constant>
                    <uniform>
                        <value>1.000000</value>
                    </uniform>
                </constant>
            </base_emission>
            <layer>0</layer>
            <texture>
                <uv_set>default</uv_set>
                <path>G:\3D work\Studio Setup\tex\kitchen.exr</path>
                <exponent>2.200000</exponent>
                <a>0.000000</a>
                <b>1.000000</b>
                <c>0.000000</c>
            </texture>
            <emission>
                <texture>
                    <texture_index>0</texture_index>
                </texture>
            </emission>
        </diffuse>
    </material>

The crash is a classic "Microsoft Visual C++ Runtime" related, I attached my installed runtimes... something missing?!

Yup, this material crashes Indigo for me, fixed for Indigo 2.2.7.
It was supposed to catch and exception, and print out

SceneLoaderExcep: Error processing texture 'C:\programming\textures\openexr-images-1.5.0\ScanLines\MtTamWest.exr': HDR textures must have gamma (exponent) = 1.

So don't use gamma != 1 with EXR textures.

[OnoSendai]

Good stuff, ono!

So far, I am finding that with texture gamma=2.2, the absorption layer transmittance color seems a bit too dark. With gamma=1.0, it seems to render more as expected. Could this be a bug? (The attached image kind of shows it but it's not the best example)

I don't think it's a bug.
Just bear in mind that the absorption layer will come into effect for each ray of light at least twice - when light enters the transparent object, and when it leaves. So that may have the effect of making the material look quite dark.
