How to add .png graffiti?
-
New to forum so apologies if its somewhere? I have a PNG of some graffiti I want to add onto a textured wall these are ones I have created in Autodesk Sketchbook copied from real on the pub.
The wall in sketchup has a textured block and when I import the graphic it looks fine but when I render it in Shaderlight it gives a black background. I have read the forums via google search but cant get to grips with exploding the image as the explode option remains greyed out. I assume it has to be applied as a projected texture to wall but need help if possible.
Having used 3DS Max cant believe how easy it is to use shaderlight and this my only issue with SU Pro and all credit to development team for a cracking product I am using on my masters and using to create games assets.
ANY advice welcome. I have access to GIMP and have created a transparent background BUT cant get it to render without a black box.

Someone who uses Shaderlight ought to be along and give you some info about the rendering end but my inclination for that would be to create a material in Gimp or whatever that combines the block wall and the graffiti and apply that to the wall as a single material.

Thanks Dave will give it a whirl but new to Gimp as well.

You can use whatever image editor you're comfortable with.
Go to the in Model materials library and right click on the thumbnail for the wall texture. Export the image and then open it in your editor and copy it to cover a large enough area. Add the graffiti and save it. then import it as a new material.

Or rather make the texture on that certain wall unique first. Right click > Make unique. Then right click again > Texture > Edit texture image and there add the png graffiti as a layer (any normal image editor can do this; PS, Gimp, Paint.NET etc.). Save the image and it will automatically reload in SU. This way you will not end up with a repeating pattern (if your texture is tiling) and it will only appear on that certain wall.
First of all, however, set your preferred image editor under Window > Preferences > Applications in SU.

Many THANKS for the advice learned a lot of new stuff in a few short hours. Martin from Shaderlight support has kindly given me help as well. The issue was very much it looked fine in SU Pro 8 but rendered out with the black background.
Have done all of these now with success. The repeating pattern also an issue that had me stumped earlier so thanks again as the technique applies to a lot of designs.
Then making a group of wall, importing the png, exploding the image before selecting as a group to recover the image and then offseting by fractions to overcome the "Stickyness" and adding in a third image the same way. BUT ALL SORTED and HD render looks great as retained the underlying texture of the odd coloured wall. In a fairly complex design it was frustrating this was a real teaser.

Now that is very much possible. Many rendering engines cannot deal with "image entities" so best is to explode them into real geometry with the image applied on it as texture.
