Cindigo 0.9 - beta 2

Thanks for B3 preview fused

I'll try to look out for bugs on the weekend.

BTW: A detailed changelog would honor your great work even more...

Probably I'm wrong, but i have done a test and it works.
I inserted an object, transformed in editable, reversed some faces and exported in obj format. Then I opened the object and normals were right, the reversed were still reversed. This means that export routine exports normals correctly, isn't it?

But, I repeat, probably I'm wrong.

Yep it works.... but Indigo has to correct/generate (?) the normals so it sometimes take 10 mins and more for big meshes before indigo actually starts rendering (totally sucks for material test etc.)

@mrmoose:

zomB is right. the normals dont get exported. indigo has to generate them. i used the c4d's .obj export when i started this exporter, but i noticed that ist useless, since there is no possibility to export the normals.

so, i had to write my own .obj export. im very happy that it works(and a little proud

). in the beta 3 release, UV will get exported right(i hope

).

with that i also had some problems. there was an issue with inverted bump maps. and i had to reverse the normals before export. the direction of face normals seem to depend on how you export the faces.

when i exported them like
f vertex1 vertex2 vertex3
the face normals were reversed.

when i exported the faces like
f vertex3 vertex2 vertex1
the face normals were right.

face normals get exported with the face itself, but the c4d .obj exporter doesnt export vertex normals (wich indigo needs).

Don't know if this is known - but if anyone has problems who look like trouble with normals or anything like that - chance global scale multiplier to 0.01 - if i've known this i wouldn't have spent 1 hour playing around with phong tags, render setting or god knows what all...

Fuse - nice work

are edge breaks supported with this new obj export?

very nice - surface shading in Indigo finally matches what I see in C4D

I noticed the C4D materials change to look like Indigo material type

yes! thats cool, isnt it?

the inverted bump maps should be a thing of the past, too!

yeap , very nice!

I did get a crash today when I tried to export some model, but there may have been some parent nulls in there, not sure

so when is higher RGB values for specular/glossy transparents coming?

parent nulls should not be a problem. can you send me the scene?

higher RGB values... thats sure to come.... but not too soon

What I noticed - when you assign a material with uvw mapped texture the scale values for the uvw have no influence. You have to generate a new uvw for that. Will this be "fixed" when the other mapping-types are implemented?

CoolColJ · Post by **CoolColJ** » Sun Oct 14, 2007 11:47 am

the co-ordinates settings have an effect though

Fuse - I'll try and find the model I was using when it crashed, I was just trying random things.

I have one question (another?!?

): what is the right way to export area light as rectangle light? Is Cindigo able to generate code for rectangle light? In which way?

Thanks, mrmoose

no, thats not possible at the moment. but i cant implement it, if you want!
