Bug when adding samples(Anim Sequences) to a 2D Blend Space

Hello guys,

me and a colleague experienced a bug in Unreal 4.13 and 4.14 Preview 1 while trying to create a blend space for our walk animations.

When dragging a new sample into the 2D Blend graph of our blend space the new sample appears at the location of another sample in the graph and the other sample appears at the location I dragged the new one.

Furthermore when 3 samples are in one line Blending seams to not work properly anymore.

Here is a video that shows both these issues:

(The project used in this video is a newly created Thirdperson Blueprint template in Unreal Engine 4.13)

We also tried to do the same in 4.14 Preview 1 and in 4.12.5. In Version 4.14 Preview 1 the bug seams to be present while everything worked without problems in 4.12.5.

Thanks for your help!

OS:
Windows 10 64 bit

Hey minecrafter338,

Back when I had originally tested this for UE-36755, it appeared to fix itself after adding the 3rd animation. I’m not sure why this has changed, but I’ve noted it on the internal comments for the bug. I’m asking that they re-evaluate the urgency of the bug.

Thanks !
Any tips how we can create our 2D Blend Space in the mean time until it’s fixed?

Hey Minecrafter338,

For now, if you’re doing a straight line blendspace, use a 1D Blendspace. If you’re doing 2D, you’ll want to have at least 4 samples on the graph. It appears to correct itself after you add a 4th sample.

Works perfectly fine, thanks!
