Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[HTC Vive] Right Eye rendering corrupted with Instanced Stereo Rendering

I noticed that enabling instanced stereo rendering for certain shaders (for example: this ocean shader scene from Piroman (https://forums.unrealengine.com/show...hader-download)) causes a corrupted right eye rendering in my Vive. Disabling instanced stereo rendering fixes the issue.

Product Version: UE 4.11

Hello fhernand,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?

  2. If so, could you provide a detailed list of steps to reproduce this issue in clean project?

  3. Could you provide screen shots of any blueprints that may be involved?

Hi Rudy,

I managed to reduce the steps to reproduce the problem:

  1. Create blank project (UE 4.11.2)

  2. Enable Instanced Stereo Rendering in "Project Settings -> Engine -> Rendering"

  3. Disable all VR plugins except Steam VR (probably not needed)

  4. Create a material (Resulting graph is attached as screenshot)

  5. In the material graph, create a Texture Sample node and assign any image (e.g. a Normal texture)

  6. Create a WorldPositionWIthScale node and connect the XY attribute to the UVs attribute of the Texture Sample

  7. Create a Constant Node and connect it to the "Divisor (V3)" attribute of the WorldPositionWithScale node. Set it to 1000

  8. Connect the top output attribute of the Texture Sample to the Normal attribute of the Material

  9. For the Material, under Tessellation settings, set the D3D11Tessellation Mode to "PN Triangles"

  10. Assign material to the Floor mesh in the scene.

  11. Start VR Preview

Result: The right eye shows an unexpectedly distorted view of the texture.

Regards Felipe

I have the exact same problem when adding a star from this asset https://www.unrealengine.com/marketplace/fx-star-starter-kit-va

I had no problem before activating Instanced Stereo Rendering

Disabling Tessellation in the material also removes this problem btw.

Spirtes are not showing on my right eye. Deactivating Stereo Rendering fixes this problem.
