Goodnight Moon - Indigo Render

I needed a new project to get me motivated and thought it would be fun to model some of the objects in the Goodnight Moon book. I will be applying my own style and may or may not do the complete scene. Here is my progress so far, a comb, some mittens a bowl full of mush and a lamp.

The lamp shade is not at all what I intended. Can anyone explain how to make a semi transparent fabric in blender for use in indigo? I wanted a cream-ish off-white lamp shade where the light would come through a small amount. Anyone have some suggestions?

…Holy frickin’…

I rememberthat book. I remember that book! That may have been my favourite book as a kid. That’s awesome, man! XD

I dunno if you can make a transparent object, you could make it cream-coloured and set its emit value to a medium amount to make it LOOK like light’s shining through it.

Wow, keep making it.

That’s an interesting suggestion. I was hoping that indigo could do it properly. So, if anyone knows how, please let me know. If not, I can try your suggestion. That might look pretty good.

I got the lamp shade to look closer to the color I wanted:

But when I tried turning on some emit, it did this:

I’ll keep looking around…

It’s red because it’s shining through red glass?

No, the material was the exact same as when it was not red. All I did was turn on emit. Very strange.

Could you maybe show us the part of the xml file there is about the meshlight…? I am not a indigo pro but it could help us locate the problem :slight_smile:

Here is the xml without emit:


    <material>
        <name>LampShade</name>
        <diffuse>
            <colour>1.000 1.000 1.000</colour>
            <albedo_texture>
                <uv_set>uv</uv_set>
                <path>lampshade.jpg</path>
                <gain>1.000000</gain>
                <exponent>2.300000</exponent>
            </albedo_texture>
        </diffuse>
    </material>

And here is the xml with emit:


        <material>
                <name>LampShade</name>
                <diffuse>
                        <colour>1.000 1.000 1.000</colour>
                        <albedo_texture>
                                <uv_set>uv</uv_set>
                                <path>lampshade.jpg</path>
                                <gain>1.000000</gain>
                                <exponent>2.300000</exponent>
                        </albedo_texture>
                </diffuse>
        </material>  

That doesn’t seem right, they are the same… hrmm…

Would it have something to do with the fact that diffuse is set to 1. 1. 1. ? I may have read there are issues with this…
Or was it with Yafray?

Be well

I think you misunderstood me… I was talking about the part in the xml that has the <meshlight> tag… :slight_smile: But I really can’t think of a reason your light should turn red… it’s pretty weird

edit:

And btw you should avoid using <colour>1 1 1 </colour>… If you use it your image is going to render muchh slower… use 0.95 or something like that :slight_smile:

I’ll get back to you on the meshlight tag.

Sorry for the delay on the mesh light information. here is what it creates when I enable meshlight on that mesh:


    &lt;meshlight&gt;
        &lt;pos&gt;10.158867 11.230408 4.097916&lt;/pos&gt;
        &lt;scale&gt;1.0&lt;/scale&gt;
        &lt;rotation&gt;
            &lt;matrix&gt;
                0.500000 0.866025 0.000000 -0.866025 0.500000 0.000000 0.000000 0.000000 1.000000 
            &lt;/matrix&gt;
        &lt;/rotation&gt;
        &lt;mesh_name&gt;Tube&lt;/mesh_name&gt;
        &lt;spectrum&gt;
            &lt;peak&gt;
                &lt;peak_min&gt;600&lt;/peak_min&gt;
                &lt;peak_width&gt;500&lt;/peak_width&gt;
                &lt;base_value&gt;0&lt;/base_value&gt;
                &lt;peak_value&gt;50&lt;/peak_value&gt;
            &lt;/peak&gt;
        &lt;/spectrum&gt;
    &lt;/meshlight&gt;

Hi there…

The problem is that you are using the peak spectrum… You tell your meshlight to start at a frequency of 600 nm and continue 500 nm…
If you look at the schematics here you can see that those wavelenghts lie in the red area… You should probably use the blackbody emitter instead, but I don’t know how to control that in blender… I usually edit the xml file instead :stuck_out_tongue:

If what I wrote is completly wrong then please somebody correct me…

btw you update is looking good… It’s going to be hard to get the feeling of the original, but just go for it :slight_smile:

Hrmm… well that is disappointing. I am trying to avoid too much file editing as it has to occur everytime I tweak the model in blender. I will leave it as is for now and consider it as a tweak down the road.

I added a chair today:

Not like the original, but I hatedt that original chair.

The chair is looking great :wink:

I looked in the blender exporter, and it seems that if you have a translucency their is higher than 0 then it is goiong to be exported as a peak type… If it is zero you can control the strength of the blackbody using the amb slider :slight_smile:

Heine

I turned the translucency off and the emit up to 0.3 and the shade looked very dark… darker than in the current renders. I will try increasing it more, but for now, I have it with tran on (at 1 I think) and no emit. Here is the latest:

This could be the awesomest thing ever. Of course, I’m speaking purely out of nostalgia.

Is there any way to make a sun lamp cast light that looks like moon light? I got rid of the sun lamp but would like to replace it with a “moon” lamp. Right now I am lighting the scene mostly with a light emitting plane on the ceiling.

Oh man, the nostalgia! I used to LOVE that book! heheh. Looking quite good so far, definitely want to see this finished :slight_smile:
