[Software] LDD2PovRay

[Cult_Of_Skaro]

By the way, can we get bbqqq's ingenious timesaver trick for transparent parts in the index? It's hugely helped the renders I've been doing.

[Flipz]

I tried playing with lights earlier, and I never understood, why the coordinates are wrong even though I copied the exact numbers! Because the light was at the corner! All I need now is a database with the size of the most common pieces that can be used as light sources.

Yeah, that's because LDD defines the coordinates of the brick based on the corner. You have to adjust the numbers a little bit (usually by less than 1) until you get the light where you want it--it will take a few renders, but you can easily stop the render after 1 or 2 passes if it doesn't look right.

[Cult_Of_Skaro]

So, I read you can rerender a portion of a model. How does one do this without sending the thing through LDD2Povray again, thus erasing the INI?

[JM1971]

Is there a file somewhere that controls which bricks get part materials and which don't? There's a lot of slopes that end up with the "sandpaper" texture that have no business with it.

Just found this out, add this line to the top of the .pov file.

#declare ldd_normal_roughPlastic_255 = normal { bumps .005 scale 1 turbulence 0 }

#declare ldd_normal_roughPlastic_255 = normal { bumps .005 scale 1 turbulence 0 }

Thanks, but not really what I'm looking for. As far as I can tell, that just controls whether or not any bricks in the scene get the texture, not which ones do or don't.

For example, I wanna be able to render the this, but have only the full slope be textured.

[JM1971]

Try contacting the guy that made LDD2POV... http://ldd2povray.lddtools.com/index.php?p=1_10_Contact

He's quite helpful.

For example, I wanna be able to render the this, but have only the full slope be textured.

Includes directory contains file ldd_part_materials.inc. At the end this file contains items in array named ldd_part_slope_materials.

For example:

#declare ldd_part_slope_materials[2449] = ldd_part_material_roughPlastic + ldd_slope_inverted;

#declare ldd_part_slope_materials[2875] = ldd_part_material_roughPlastic;

means that part 2449 has sand paper slope on the bottom (that's why ldd_slope_inverted). 2875 has slope on the top.

Remove line

#declare ldd_part_slope_materials[92946] = ldd_part_material_roughPlastic;

and the problematic part will not have the sand paper look.

[Leewan]

Does it work the other way round ? I mean, it is possible to give a "sandpaper" texture to regular, smooth parts ? Could be fun.

[hrontos]

Yes. The same file contains lines like:

#declare ldd_part_materials[2335] = .....;

If you put there:

#declare ldd_part_materials[2335] = ldd_part_material_roughPlastic;

Part 2335 will be rendered with sandpaper texture.

Do it for all parts from 1 to 99999 and all parts will be like that. Excel may help you to generate needed lines.

[Leewan]

Thanks for the tip, hrontos, but it does'nt seem to work for me... x/

I tried to give some basic bricks (1x1, 1x2, 2x2, 2x3, 2x4) the textile texture, but they are rendered with their usual texture.

[hrontos]

Do you have "Use part materials" on the "Materials" tab checked?

[Leewan]

Yup. I also tried to uncheck Use custom materials, but it doesn't work either.

Note the two lines:

#declare ldd_part_materials[3003] = ldd_part_material_textile;

It should give you "textile" pyramid. Modifying material file should give the same result.

Hi

Im having some trouble with LDD to Pov Ray...

when i try to render pov ray shows me this message :

Possible Parse Error: Cannot find file ´C:\Useres\Jo´, even after trying to append file type extension

Parse Error: Cannot open input file

both pov ray and ldd-to-pov ray are 64x bits the directory of LDDIncludes its ok and my O.S is windows 8

i think that pov ray is no able to access the file directory wich is : C:\Useres\João\Desktop

Edited April 21, 2014 by miroskes

[legolijntje]

Have you tried to run it as administrator?

[miroskes]

yes i did, both of them :/

[legolijntje]

Hm, that's strange that even when running as admin they don't work.

Instead of using a file from the desktop, try runnung the file from the "my Documents" folder. And make sure all the settings in LDD2POV-ray have the correct paths to all the necessary things.

[miroskes]

got it, my folder as a "~" on the "a" of "João" and pov ray does not recognize chareters like "~" xD

I have a question regarding decorations custom decorations. It seems that they are rendered darker than they should leading to colour mismatch between brick and decoration.

Here is an example of standard decoration.

It renders in almost correct dark red colour, but it is way to bright in LDD. So basically to have a good cloud match one have to brighten custom decorations.

Is there a way to increase their brightness when rendered. Maybe there is some kind of statement to add to pov file? Or maybe there is a pallet of RGB values that are used in LDD to POV Ray that can be used for colour matching?

My suggestion is to use transparent PNG. This means, make the area of decoration that is supposed to match brick color transparent. And it will work for any brick color.

Yes, I use transparent PNG files where it is possible, but how to be in case such as shown above or similar. The legs itself is yellow, "dress" is supposed to be dark red, if colour is mismatched it easily seen, as there is a dark red hip part right next to texture.

It looks like for some reason TLG considered this problem in some of decorations. Some of dark red decorations are actually brighter than dark red colour itself, but others not. Same goes for some other colours.

I guess I'll need to experiment more with colours to match them. But I was wondering if there is a way to change brightness of all textures used in scene with some pov-ray statement?

Editing the ldd_default_colors.inc will crash ldd2pov if it is not the exact same size as is it by default, you can add/remove spaces to do that.

But a better way is press on the object in ldd to reveal the colour number in the bottom left of the screen, then add a colour declaration just after..

#include "ldd_default_colors.inc"

In the .pov file.

Colour declaration...

#declare ldd_colors[47] = rgb <255/255, 255/255, 255/255>;

Example: colour 47 set to white.

@hrontos : Thanks, I'll render it as soon as possible, but first I need some help.

Last week, I modified the ldd_part_materials.inc file to try to give the parts alternative materials, but it didn't work, so I erased my modifications. Unfortunately, right after that, when I tried to render, I had this message : "\\.\LDDIncludes\ldd_default_colors.inc" line 20: Parse Error: Illegal character in input file, value is 80., with the #include "ldd_colors_declarations.bin" line highlighted.

I reinstalled both POV-Ray and LDD2PovRay, I set up the correct paths, but the problem remains. x/

Delete the whole LDD2POV folder which the ldd_defailt_colors.inc files was in and when you convert a ldd file it all gets replaced.

[Leewan]

It doesn't work, the error message is still here. x/
