dipstick

It's a simple math problem. Assuming you want to create an 8x10 template @ 300dpi.... 8x300= 2400 pixels 10x300= 3000 pixels Make your template 2400 x 3000 pixels. Adjust as needed for various dpi requirements.

I found this kinda interesting so gave it a go using lots of different blending modes.

You can do that because you're hosting it on your server. I don't know any hosting site that supports WebP, usually only gif.

Why do you think that animated png is smaller file size than gif? That's never been the case in my testing done years ago. Animated png makes better quality, but larger file size. WebP is definitely more efficient, but support for it is very poor.

Merge them down manually.

Delete the background leaving only the car object and transparency, then flip layer.

Yes, I would also recommend to use the gradient tool in "Radial" mode. Set background color to white and foreground color opacity to 0.

I wonder if you are talking about something like "Symmetry Painting" found in Gimp. It allows you to draw on multiple parts of an image at the same time.

Wow, I had no idea. It's such a tragic loss, as he was very talented and obviously a great person. He worked tirelessly on tutorial conversions to pdf. He will be missed by many.

Example:

Though not quite as advanced, you could try "Illuminate 2D" filter in G'mic plugin.

Direct link to Shape3D_1_2_6_0.zip via WayBackMachine circa 2010.

Very nice plugin, thanks.

You're right, I edited my post.

I would love to test out this filter, but it won't run on my version of PDN (4.0.13). I guess I'll have to setup a Win10 VM and update PDN to try this plugin out.

Made the spaceship in blender, everything else made in PDN.

The feature you're requesting is called Layer Groups. I don't believe PDN supports layer groups. I also doubt a million people want this feature. If it's important to you, then try Gimp, as it has layer groups. https://www.lifewire.com/introduction-to-layer-groups-in-gimp-1701685

Too easy. Use "Midora's Animate Images" to make the animated gif using two layers.

If you add some roughness to the shader, it will reduce the reflection. It's a matter of what you want. You can download blender and see for yourself. I can post the blender file if you want. Blender is very hard to learn though and I still know next to nothing about it. This is actually the first object I've sculpted yet. I have a long way to go. Even on this textured vase, you can see some reflections of your image.

And here is your vase shape.

Here I used "Principal Shading" in blender on this chain link. I used your environmental image as an environmental map for the "World". It can use either equirectangular or mirror ball.

Excellent work. This looks a lot like Blender's equirectangular diffuse. I need to check this one out.

Be sure to select 32-bit when saving to PNG. This will include the alpha channel for transparency.

Dang, the comp is closed and I just finished my Earth render. Guess I'll have to vote.

Well done lynx, I didn't think of Edgeshader.
