How to export only selected objects in Blender

By default Blender exports every item in your scene when you choose File – Export. That’s not so good if you only want to save out a small portion of a large scene.

But it doesn’t have to be that way: there’s the often overlooked Export Options on the right hand side, on the same page where you choose the file name and folder. The very first tick box is labelled Selection Only. Tick it, and only your selected object will be exported.


There are plenty of other cool options in this handy dialogue too, such as Material Groups, Polygroups, Scale and so forth. Well worth checking out!

COOL BREEZE Textures – now available at Renderosity


Here’s a texture set I’ve made for the Jolina Dress by my friends from Rotenburg and der Wümme, outoftouch. Although we don’t actually know each other, I feel a special connection because I used to live in Verden an der Aller, which is a mere stones throw away from Rotenburg. It’s a small world!

How to open multiple images as layers in Photoshop

Photoshop CC splashDid you know there is a way to open several images in the same document as layers in Photoshop?

It’s a real timesaver if you have several renders that all need to be composited onto the same background for postwork.

It’s really easy to do:

  • open Photoshop (duh!)
  • head over to Scripts – Add Files to Stack
  • browse for several images, or choose a whole folder, or choose any open images you have
  • hit OK and let Photoshop go to work

When it’s done you’ll have all images open in the same document, stacked on top of each other in a new layer. Thanks to Julianne Kost for this valuable tip!

How to create a HDRI image in Photoshop

Photoshop CC 25yrsPhotoshop can combine multiple images into one and save them as HDRI, which allows us to use them in our 3D renders – either as 360 degree backgrounds or as light sources.

The way to do it has changed several times over the years – so here’s how this works in Photoshop CC 2015.

How to fix “The interface of shader xxx is invalid” in DAZ Studio

Sometimes, the 3Delight render engine in DAZ Studio can throw a hissy-fit and complain with the following error message:

3Delight message #45 (Severity 2): S2069: the interface of shader '/Users/versluis/Library/Application Support/DAZ 3D/Studio4/temp/shaders/brickyard/{407f8e5c-3a9b-4708-b5e5-799ff1fe7c1d}/shader_Surface.sdl' is invalid
3Delight message #45 (Severity 2): S2051: cannot load shader 'brickyard/{407f8e5c-3a9b-4708-b5e5-799ff1fe7c1d}/shader_Surface', will use 'defaultsurface'

3dl2-4This problem occurs frequently on complex shaders, such as human skin. I have no idea what causes it, because it appears to happen randomly and without reason. Here’s an example of how scary such an error can manifest in a render.

Even saving the scene and loading it may not resolve the issue. Which can be extremely annoying.

Lucky for us there’s an easy way to fix this, thanks to a tip from jestmart on the DAZ Forums. All we have to do is remove the temporary folder in which 3Delight compiles shaders to make rendering more efficient (where I guess sometimes an error can occur). So it’s not the scene or the actual shader that has a problem, it’s just the compiled version of the files before the engine can go to work.

Here’s what we can do to fix it: remove the brickyard folder in DAZ Studio’s temp folder. On a Mac it’s located in /Users/you/Library/Application Support/DAZ 3D/Studio4. Here, navigate to the temp/shaders folder and remove the brickyard folder (the error message shows the full path to that folder).

On a Mac, navigating to that folder via Finder only works with a trick, because the Library folder is hidden by default. You an either use the command line to navigate there, or use Finder and hold down ALT while you click on the Go menu item (this will show the Library option).

When the brickyard folder is deleted, simply start that render again. 3Delight will go ahead and re-compile all missing shaders – this time hopefully without adding freaky effects. There’s no need to restart DAZ Studio. Nice!

How to combine several saved selections in Photoshop

Sometimes it’s necessary to select more than one saved selection in Photoshop. And I was often wondering how to do it, thinking there had to be a way – until I discovered it by sheer accident today while pressing seemingly random buttons.

Usually I call up a seed selection by heading over to Select – Load Selection and choose the channel I want. But that way I can only bring up a single selection at a time.

Lucky for us, there is another way: we can display selections using the Channels Tab. Usually it’s next to Layers Tab – but in case it’s not showing up, choose Window – Channels to display it.


Click on a channel and it will display the corresponding parts in your main window. That’s not what we want, I just thought I’d mention it.

To turn a single channel into a selection, CMD-click / CTRL-click on it. As you hover with your CMD key pressed down, the selector will turn into a little square with a dashed outline, indicating this would become a selection (I guess).


To select more than one channel, we can simply use SHIFT while clicking (only works on channels other than RGB, Red, Green or Blue – i.e. it only works on saved selection channels). If we combine this with holding down CMD, then we can select multiple selections at once.

Let’s see an example


In my case, I have two saved selections for a zipper, and I’d like to create a selection that incorporates both of these at the same time. Hence, select the first channel, then hold down SHIFT+CMD (or SHIFT+CTRL on Windows) to select another channel. Note that the cursor turns into a little plus icon (you’re adding to a selection).

Hey presto, both areas are selected in my main view!


It gets better: you can also subtract from a selection, by holding down ALT in addition to SHIFT and CMD. So if we’d like to remove a channel from our selection, we’ll hold down SHIFT+CMD+ALT, then click on the undesired channel. Note that the cursor turns into a little x icon (indicating that you’re removing something from your selection).


And that’s how we deal with multiple selections in Photoshop 🙂

My new HP Z600 Workstation

photo-sep-24-16-22-52I’m as excited as a kid in a candy store – because last Monday my new (old) HP Z600 Workstation has arrived! Built and sold to the government in the summer of 2009 for roughly $5000 (give or take a grand), it came to me via an eBay auction for $171 plus postage some seven years later.

Equipped with two Intel Xeon 5560 processors, no hard drive, 4GB of RAM and only a COA sticker for Windows Vista, I had a little bit of work to do to get it all going:

  • get a USB keyboard
  • get a power cord
  • get a graphics card
  • perhaps grab some more RAM
  • find a network cable
  • download a copy of Windows Vista (not easy to find in 2016)

I wanted to use this machine for 3D rendering in both Carrara and DAZ Studio, so for the latter I decided to buy an NVIDIA GTX 970 graphics card. I had to do a few internal modifications to the machine to make it work – but work it does, and it was a lot of fun to get this rig going.

Without further ado, here’s my Z600 story.

How to create a Smart Prop in Poser

Yesterday I’ve written about how to create a Smart Prop in DAZ Studio, and today we’ll learn how to do it in Poser.

The principle is the same: model your 3D object as you wish, then import it – or load and create a primitive in Poser. I’ll do the latter and give Andy some exciting earrings (even though he doesn’t have ears).


As you’ve guessed it, these are just two sphere primitives. Poser can’t create its own, but you can load a variety from the library under Props – Primitives. I’ve scaled them and moved them into place. Continue reading How to create a Smart Prop in Poser

How to create a Smart Prop in DAZ Studio

Smart Props are little items of geometry that can follow another object without the need to be completely rigged – unlike conforming clothes, which need to have the same skeleton and rigging as the parent figure.

Smart Props are great for things like jewellery and other ancillary items. Let’s see how we can create one in DAZ Studio.
