Here is the test:



And you see now my problem,the light. I have one Sun lamp,set Sunsky type in script,and all i have is that black render,unusefull.Some ideas what problem turn my render so black?I set dirc. of the Sun and dest.also.

you could use reinhard tonemapping(if you havn't already) and try
following parameters for example:

Code: Select all

    <tonemapping>
        <reinhard>
            <pre_scale>1</pre_scale>
            <post_scale>3</post_scale>
            <burn>0.7</burn>
        </reinhard>
    </tonemapping>

hope this helps

Where i can find this reinhard tonemapping?

[meekly]

I found it in .xml file.Can you telll me what exactly do this "rainhard"?Some explanation ?In blender cant find this setting.

Reinhard tone mapping is a technique to make the shadows and midtones in a high dynamic range image brighter while avoiding to clip the highlights. It is a form of compression. The full Reinhard also has automatic dodge and burn but this is not implemented in indigo yet.

Thanks!
Also i see this things in .xml file:

<pre_scale>1</pre_scale>
<post_scale>3</post_scale>

What is the meaning of that settings?What they do?

[ryjo]

<pre_scale>1</pre_scale>
<post_scale>3</post_scale>

What is the meaning of that settings?What they do?

I think that pre_scale multiples all pixel values (luminance) with a constant before applying the algorithm. post_scale multiplies after applying the algorithm.

Increasing pre_scale above 1 has the effect of making the mid tones and shadows brighter. Increasing post_scale above 1 makes all pixels brighter, but will start to clip the brightest pixes to white (digital clipping). At least, this is how I understand it.

Hope that this helps

BTW does

Code: Select all

<pre_scale>1</pre_scale> 
<post_scale>1</post_scale>

guarantee a neutralised tonemap ? If so could be usefull as a starting point for figuring out how this works ???

[ryjo]

Hi,

Reinhard tonemapping is a non-linear transformation between input and output. Because of this there is no neutral setting. post_scale is not part of Reinhard as far as I can tell so for this a setting of 1 would be a neutral setting.

Thanks ryjo for comments .

Here is one update i have:

[meekly]

nice!

i'd add a nice HDRI map to illuminate it,
and use a good carpaint.

greetz,
radiance

You mean to put HDTR in UV and illuminate ?How i can put carpaint when i have nkdata?Maybe like tex?

[Phil]

looks really nice,

Super model!
I find the color of the tyres better, but also to shiny now.

regards, Phil

[CTZn]

Much better !
