So I am used to Blender.

In octane how do you map textures?

You need uv-mapping. Mapping got to be done previously in your 3d suite. You need to use uv-mapping inside blender. (As in most cases its necessary to use uv-mapping for nice placed textures)

good luck:)

Hey how do you make it so that the textures do not repeat its self?

Create a bigger texture or make it seamlessly tiled, so that the repetition is not obvious.

Hi,

I'm an archviz artist / architectural designer using blender with yafaray, luxrender and the usual open source stuff. I gotta say, Octane is the single best thing I've ever found for 3d since blender, its amazing!!!

This is my first post on the OR forums, so I hope that this is useful to someone...

On this topic, I was wondering about how octane's texture scale/rotation/positioning relates to blender's mapping, particularly where I use 'Cube' mapping co-ordinates (which place textures according to the X-Y-Z co-ordinates) so I rendered out some tests. (BTW I use 'cube' to map the texture co-ordinates for stone walls within blender/yafaray/lux)

I was pleased to discover that while I knew that Octane relies on there being a UV map in order to place the 2d texture, there is a way to generate a UV map which places the texture in the right orientation and scale. My method is as follows

1)In blender, after finishing the modelling of the mesh making up the walls, I go into edit mode (Tab) and select all vertices.
2) Press U to give unwrap options.
3)Select 'Cube Projection'.
4)Go into object mode.
5)Render via the export script

And voila! The bricks are in the right place at the right size aligned as they would be in blender.

I attach a VERY rough test to illustrate a stone texture.

BTW, if a developer reads this, a facility to locate the centre point of a texture, with its real-life size and 3d alignment would be fantastic... Otherwise how do you scale/locate things like ceiling tiles accurately? Perhaps if this could be mapped from an empty in blender????

Thanks for reading!

Rob

Ah, cool, but i think you should post this in Blender's forums :)

Oh, sorry, wrong forum section! I'll copy it across for those who may need it!

Thanks :)
