Feedback Required v1.13 - new Portal blocks: Tech portal (with frame) and “free standing” spherical portals

I know others have mentioned this as well but really wish these could work for teleporting ships.

 

Some feedback on the new portals:

First, the new TechPortal looks really nice. I could see that getting used in story POIs.
There's a texture glitch on it though, like one of the textures is super low resolution. Easy to spot if you paint it black:




Allowing you to place blocks within the portal frame is really cool and will allow for some great integration into POIs and such, but is there any way to fix the Z-fighting when placing blocks inside it?




I don't like how the portal itself darkens everything behind it, like it's a plane of tinted glass. An energy portal would glow brightly and obscure things behind itself, but it wouldn't do it by making them darker.
This is most noticeable on the largest portal size but you can see it on all the portals and it doesn't look very good. It wouldn't be as noticed if used against a black space background but anywhere where a background can easily be seen it'll be very noticed.
Ideally that black background just shouldn't be there to give a smoother transition along the edge of the energy vortex.
It's not bad on the old portal style because it has a built in frame, is smaller, and is actually a lot darker that looks better.




Also, I know this keeps being mentioned, but these larger portal sizes would be far more useful if they could teleport ships. I just don't see a use for a gigantic 87x87 sized personal portal. Even the 5x5 is a bit too large to really fit into anything for personal transport to work in with the block shapes we have.
