The Intel Denoiser might be useful here.
Check Denoising Data in Properties Panel > View Layer
Check Use nodes in Compositor
Add the Denoise node and connect it like this
Now render your image and it will be automatically denoised.
If you're not going for photorealism, you'll be better off using Eevee Render Engine.
It can be changed in Render Tab ...
I saw on blender-today, yesterday, someone brought this question up with curved surface low poly artefacts. Adjust the angle or shape of the poly faces with rotation or sub-divide to see if that helps.
Note: This is for Blender 2.79
I think the mode you mean would be Edit Mode. To insert a background image, press N then scroll down to Background Image. Expand the panel then click Add Image. Click Open and select your image file. Make sure the checkbox next to Background Image is ticked! And you can use any image, but make sure it is a compatible file ...
I think there is no special mode for this. Once you have a background image added to the scene (Shift+A > Image > Background), create your first primitive in Object Mode, then switch to Edit Mode and start modifying and extruding your model based on the background image.
Finally, I managed to combine image parts together with looping nested arrays. Although the script itself is not the most beautiful... I mark this answer to correct now, but if somebody is doing better that works in this context, I'll change it.
So here is "monster" that I've used in this case:
# First I need to order rendered part names correctly
There is many possibilities to do separation, but also with so many limits, that make it almost nonsense.
First limit is 8bit depth of your JPEG, should be 32bit like Open EXR. 32bit gives you much wider color range (especially to separate sky).
Second limit is bouncing light that make it totaly impossible to separate all indirect light for re-lightning ...
Simple control of emission without affecting source appearence.
Quite surprised how light wrapped Sphere just from front direction.
But object is not lighted from front (black faces in center), because there is not any light behinde camera.
You can also use the image as World material mapped for Camera window (Texture ...
Here's one possible way to do what you want, if I understand your request properly.
The mix shader on the lower left is just the one that comes from the Images as Planes addon. That could just as easily be the direct Color out of the Image node. What I'm doing here is crushing the darker areas so that the image is mostly just the lights and the skyline. ...
Good news! I managed to figure it out. I found this thread here, recreated the node map in the last picture on that thread, and lowered the emission strength so the villager wasn't blindingly bright.
Edit: Turns out replacing the Emission node with a Diffuse BSDF node works as well. Good to know.
The white spot in your render is just a reflection of your Point light.
To make it also visible in the Viewport, you have to enable your Scene Lights.
You seem a bit confused about using the Bump node.
If you're using it with a color image, add a color ramp to make it BW and to control the contrast.
There's no need for a Displacement node.
Finally after investigations I got something to work. Here is example blender file where is script that exports merged image. It works properly when using images that are rendered with "full final size" where is transparent section included and other with "cropped borders". Look below for a better understanding.
And here is script that is also included in ...
OK. This answer doesn't necessarily use python, but it achieves the same result.
Say we have 4 pictures, and want to combine it into one image in Blender. There are many ways to do it. I'll give a few examples:
1) Individual faces for individual materials
You can assign the images to individual faces in Blender. I'll use the example you provided.
I have ...
The answer to my question in case anyone else runs across this problem, was the sort order of the images
Image 1 shows I clicked on the display icon
Then I changed the display mode from sort by date to name of the images.
Not sure why date order did not work, but because it was in the wrong sequence only one image was imported.
In image 2 you can see all ...
Mac only (although likely similar for other OS):
Save the image with the following settings:
Then, double-click the image in Finder. Select Tools in the top menu bar and then Adjust Colour.... Select Auto Levels.
This worked for me, but it may not work for all images, otherwise you can adjust the colours however you want.
It appears that alpha channels no longer work with images stored in empties in Blender 2.8.
The workaround, which is probably a better solution, is to load the image as a material into a plane object. The scene then must be viewed with Viewport Shading either "Material Preview" or "Rendered", as the material will not be visible from "Solid" mode, as ...
