How to combine rendering techniques?

lagodue — Thu, 11 May 2023 10:37:14 GMT

I am starting a renovation project and would like to show a presentation drawing where the existing conditions in normal, hardline, straight line mode, but use "sketch" rendering for the lines showing new work. Any thotz on how to do this?

With manual labor (masking, erasing, painting depending on the step and application), take two renderings from ArchiCAD (one sharp, one sketch engine - same camera position) and layer the sketch on top of the sharp one in Photoshop.

Good results for this kind of thing are possible quickly by someone experienced with Piranesi, but if you do not already own it, then the cost and learning curve may be a roadblock on this project.

A plus of the Photoshop blending method - which has many variants (opaquely erase to allow color or texture from layers below to come through, for example) ... is that you can set up layer masks ONCE and then merrily revise the model, re-render, and then use the revised renders with the established layer masks to quickly incorporate revisions without having to repaint the entire collage.

(Note: only the full version of Photoshop suports layer masks. Maybe Photoshop LE 3 does, but Photoshop LE 2 does not.)

These things can also be done in compositing software such as Combustion & After Effects. And these work for animation too!

(Not cheap, so definitely not for casual use)

So we have Dwights book on Lightworks rendering. And arm swinging.
David Nicholson-Coles book on GDL magic.

When are we going to get Karl's book of nifty AC tricks?

There's gold in them there tips...

Cheers

Thanks, Cameron! As Jimmy Durante used to say, "I've got a million of 'em!"

Am thinking about shifting to writing mode later this year... stay tuned. 😉

Regards,
Karl

I made this rendering with the same method as Karl - LW and sketch rendering mixed in PS ...

Very nice. How long did it take to composite the different images?

Thanks for compliments Mixing the images didn´t take too long - just an hour or two of playing in Photoshop ...

"Composting" in AC

I needed to show the elevations in a 3D fly-around video and came up with this.
The dimensions are backwards as the complete video uses the far elevation only when the camera is on that side.
I rendered 4 separate files, turning off the elevation side that was closest to the camera and repeating the first & last frames in successive files so that the final video looks as though the elevations fade out as the camera gets to that side (using transition fades in the video editing program).

If this looks useful, I can describe the technique to get an exact match of the elevation scale & position to the model.

Great stuff!
