Hi Guys,

I can render an image in 2.5 via Luxrender now. However when I use a mesh with Textures and bump maps I get the above errors in the LOG Tab of Luxrender.

I have the Material set to MATTE, I hit the T for Textured Diffuse Colour and added 'Texture' then for Bump Map I hit the T also for Textured Bump Map and added 'Texture.001'.

Am I correct in this for adding image textures?

Thanks
Aidan

You need to ensure that the textures you've assigned to Diffuse and Bump are of the correct type. Diffuse needs a 'color' type texture and bump needs a 'float' type.

This table here will show you which texture types to use for material parameters: http://www.luxrender.net/static/materia ... ters.xhtml

and this table (the column headers) shows which types the textures are (use the color coding): http://www.luxrender.net/static/texture ... ters.xhtml

I think the Blender console will also tell you a bit more detail about texture assignment errors.

Wow - I do have a big learning curve.

Could someone define a 'color' type texture and what format AND a 'float' type texture and what format??

In Lux, a texture is not the same thing as 'Image file'. A texture defines a spatial-pattern that can be applied to a material or texture's channel (diffuse, bump, etc).

The table I linked above (http://www.luxrender.net/static/texture ... ters.xhtml) shows the textures that Lux supports.

If you're wishing to use an 'Image file' as a texture, you should use the 'imagemap' texture from Lux's texture types. In the UI panel for 'imagemap' you will see a switch for the 'color'/'float' mode. Lux supports most of the common image file formats with its imagemap texture - jpg, png, tiff, tga, exr etc.

If I select the blender texture tab while LUXRENDER for 2.5 is enabled I get this:



The only texture type with Image is Image or Movie as you can see. I cannot see any Imagemap texture type? Am I missing bits? With Luxrender selected this is all the functionality I have under the texture tab!

Maybe its a Blender 2.5 thing?

You have selected Blender's 'Image or Movie' texture type, which is not supported by Lux.

Under the 'type' dropdown list, choose 'Plugin' - then you will see the Lux texture types

DOUGAL2.

YOU ARE A STAR ... that was one real nice nugget of info, did not know this.

Cheers

Hy,

What would you suggest if I dont have the Plugin Type?

[wicked208]

if you dont have the plugin type, dont worry, just down of type you see luxrender type, and follo the steps, image maps etc...
