How to reproduce missing Specular functionality in Blender 4.2?

C

Christoph Werner

Some important shader functions to control special values were removed in Blender 4.2. The transmission roughness for example. There is no way to reproduce it. This is important, if you update old peojects or expand them by new client wishes. You have always move back to the old Blender version.

Another functions differ from older versions and can result in trouble. One of those functions is the "Specular" option in the Principled Shader. It got new but lost also some functionality.

Question: Do someone know how how to reproduce the Specularity behavior that is known in old blender versions? See my example in Blender 3.6.5. How to reproduce the samespecularity in a metalness shader in Blender 4.2?

Blender 3.6.x. Basically the same values, but different result.

How can I start a remote lsp server and specify a specific host and port to connect to with eglot?

I am developing directly on a development container in a container on a (remote) Kubernetes cluster. The container has an ssh-server which means that eglot can start the remote lsp-server through ssh.

Additionally I've set up port-forwarding to forward a port on the local machine to the lsp-server port on the container. In this way eglot can connect to the lsp-server through a port on my localhost.

However I am not able to find the correct commands to automatically make eglot start the lsp-server remotely and subsequently connect to the server on a local port.

With the following command added tot the eglot-server-programs I can get eglot to start the remote lsp-server (by running M-x eglot). (PS I run this command after I have opened a file on the remote container through tramp, eglot seems to find out automatically that the command to start the lsp-server should be run on the remote host).

Code: 
  (add-to-list 'eglot-server-programs '((python-mode python-ts-mode) "pylsp" "--tcp" "--host=0.0.0.0" "--port" "5007"))

When subsequently I add the following to the eglot-server-programs and run M-x eglot again:

Code: 
  (add-to-list 'eglot-server-programs '((python-mode python-ts-mode) "localhost" 5007))

Then eglot seems to connect to the server and things seem to work fine.

But again, I cannot get eglot to perform the two steps above automatically. Is there a way to make eglot preform both steps above by adding only a single entry to the 'eglot-server-programs list?

Or maybe there are two seperate commands that I can run to first start the remote-lsp server and subsequently to connect to the server though the local port?

Vertices connect to Mesh

I want to connect these vertices to make a mesh, but I have no idea how to do it efficiently. I tried to do it manually but it cost a lot of time and I was probaby doing it wrong.

Separate Object into equal chunks by a grid

I have an terrain object that I want to divide into chunks of the same size. I already created a grid (black lines) with that I could slice the mesh. I want every chunk to be a separate object. Any ideas?

Decrypting base2i encryption?

We all know base64, which can be easily decoded, but there's also base2i encryption. Yes, the base is a complex number. I can only find very limited resources online about this. I'm wondering how can a plaintext be encrypted using base2i and then decrypted?

I've got this base2i encrypted ciphertext: 3030101000000000201030203010100030200020100030301030303030201000001000100000202020103010202030001010001000201010003020003020200020203000101000202010203030202020203030000030200000203000303030200030101020300010300030101020102010303020302020202010003010001

I tried to treat this as one large number and convert it to base10, but in base10 I got a complex number which doesn't make sense. Maybe I should decrypt this in chunks? Not sure how this works.

shapez2 - Why do the shape/fluid loaders have three levels?

  • ordago

  • Replies: 0
I don't understand why the shape and fluid loaders have three levels, it looks like they only use one of the levels to load items. When the bottom level is overloaded, it doesn't load items in the middle level, and if a new shape or fluid is added, the bottom level is replaced with the new item instead of adding the new items to the middle level.

Problem is depicted on this gif:

Left most loader switches between red and green fluid, and the other two loaders can only load items on the bottom level insted of using the rest of the levels.

So I don't understand the point of having this three levels. Is it for storing more of the same item? or is it to have three different items stored? How can I take advantage of these three levels?

I m trying to script that delete all faces in my scene, but not the edges and loose edges. I try many but still no good results. With GUI it works like that :

  • Select object
  • Go to edit mode
  • Select all
  • Hit delete
  • In context menu choose faces. That s it. Any hunt to script this ? Best regards, Gilles

Problemas con mi editor VSCode (Creo que es el scriptcs pero no encuentro solucion)

hace un tiempo he venido programando en VisualCode pero cuando intento correr el codigo en mi editor me da un error en la pestaña Output, el error es el siguiente: [Running] scriptcs "c:\Users\juand\Desktop\C#\Program.cs" "scriptcs" no se reconoce como un comando interno o externo, programa o archivo por lotes ejecutable.

[Done] exited with code=1 in 2.002 seconds

tengo la carpeta de scriptcs en la misma carpeta donde estoy haciendo mi proyecto y ya he intentado solucionarlo agregandola al path y una infinidad de cosas diferentes pero nada me ayuda co eso, si alguien podria ayudarme se lo agradeceria mucho.
