luxrender texture problem

im currently working on something which i am rendering in lux. The straneg thing is that when i render, it seems to only render the color of the texture and not the detail within it.
ill show you what i mean.



This is my basic scene after around 30 mins of rendering. Now the problem is that the floor texture is actually a wood texture

but it seems to be rendering only the color of the texture. Does anyone know why this is?
i don’t think its because ive not rendered it long enough you can normally see textures appear straight away.

Let me know if it would be useful to upload the .blend

thanks

You have to use Luxrender’s image texture option instead of Blender’s.

There should be another menu labeled ‘Luxrender type’, choose the image option in that menu because those are the ones Luxrender uses.

thanks for your reply. I have had a go at that and the only image option i found was image map so i tried that and the early signs of the render showed no difference. Also, does lux have a cache as when i render i sometime get parts of the model render as they used to be. e.g. the chimney breast is actually much wider to accomodate the firplace, but lux seems to render it the way it used to be when much narrower.

Did you make sure to apply the texture in the material?

Yes i assigned the texture…


the strange thing is that it renders in the preview section just not in the actual piece. Im wondering if it could be a caching issue?

Did you use a UVmap? The automatic coordinates may not work well for some cases.

well i followed the technique used in this video


to add the textures and yes i unwrapped the plane and mapped it onto the image just like in the video above. The texture mapping type is set to UV in the texture panel and luxrender texture mapping section.

Are there any errors in LuxRender’s log tab? (when using external rendering mode)

Your texture might accidentally be set to “grayscale” instead of “color” in LuxBlend’s texture tab.

nope, the only time i have got an error was when i set to luxrender image map and then changed to colour but didn’t select the path to the image. When i set the path to the image the error disappeared but still no actual texture just the colour.

very strange!

In that case, could you post the .lxm file of the scene here? The scene itself could be useful too.

Also, are you sure the versions of LuxBlend and LuxRender are matching exactly? Did you get LuxBlend from luxrender.net or from graphicall? What OS are you using?

windows 7 and i just downloading and installed luxrender and enabled it. should i have d/l a blender build? i just noticed on another project i was working on aswell thats the texture isnt coming through only the colour.

i tried attaching the .lxm file but its an invalid extension for uploading on here strangely.

hallelujah, hallelujah :smiley: finally got the floor to show. Dunno what was going on; seems to have been a caching problem or something. I deleted the floor. added a new one and assigned the texture and yer, it showed straight away. Its strange how lux seems to render stuff the way it was before changes :confused: i am having the same problem with my chimney breast too but im sure if i delete it and ad it again it will magically fix itself.
Thanks for the help!


Luxrender and Vray have a problem rendering planes, ad a solidify modifier to fix it. This might be some kind of “physical based” rendering problem that everything needs to have volume, or something.

When ever I have a ground plane without thickness it get rendered wrong.

You can disable the geometry caching thing by unchecking “Partial PLY Export” in the render settings. Then hit render again. That will force a full update of the geometry files.

thanks for that. I did however find that box today and go hmm what happens if i un tick this…render ooh, everything has updated nicely :smiley: been spending all day trying to get a different material to render, untick that box and it renders straight away :confused:

thanks for all the help guys. This should now be closed
